It’s been quite a late winter at Juniper Level/Plant Delights, with the latest-occurring single digit temperature we’ve seen since our records began in the 1970s. Plants like helleboresin bloom when the cold snap hit have recovered, although flowers that were fully open or nearly so were slightly damaged. Hellebores are really tough and, after removing a few damaged flowers, they look great.

Plants and More Plants
Some of the very early trilliums, like the Florida forms of Trillium underwoodii, were also damaged. On a few of these, the entire stem collapsed back to the rhizome. When this happens, these trilliums will not return until next year. All of the other trillium species had the good sense to wait until later to emerge and are unscathed.
One of the benefits of cold winters is a good chilling period for most perennials. Like a bear needs to hibernate, the same is true for most perennials and the longer rest and deeper chill they receive, the better they return for the upcoming season. Consequently, we expect a stunning spring display.
The fat peony buds have already poked through the ground and started to expand. We moved quite a few of our peonies last year into sunnier areas, so we have really high expectations for 2015. We continue to expand our peonyofferings based on the results of our trials where we evaluate for good flowering and good stem sturdiness. It’s a shame that many of the best-selling peonies often don’t meet that criteria.
One of the first plants to sell out this spring was the amazing mayapple, Podophyllum ‘Galaxy’. We have another crop in the production pipeline but they aren’t ready yet…hopefully in the next few months. Thanks for your patience since there was obviously pent up demand.
The flower buds have also begun on the sarracenias (pitcher plants) in the garden. Not only is pitcher plant foliage unique in appearance and its ability to attract and digest insects, but the flowers are also amazing. Each flower arises before the foliage, atop a 6-18” tall stalk (depending on the species). The flowers, which resemble flying saucers, come in red, yellow, and bicolor.
Pitcher plants are very easy to grow in a container of straight peat moss, and kept sitting in a tray of water. In the garden, sandy soils or a combination of peat and sand work great. Just remember…no chemical fertilizers or lime nearby…they need a pH below 5.0. Pitcher plants also like damp feet but dry ankles, so growing them in a swamp is a no-no. We hope you’ll find something you like from our selection of ten different offerings.
In case you missed it, we recently added a number of new helleboresto the website, many of which are available in large enough quantities that we can offer quantity discounts. Of course, this will be the last of our hellebore crop for 2015, so when they’re gone, they’re gone for the entire year.
Thanks to everyone who visited during our winter open nursery and garden days…many braving some unseasonably cold weather. Remember that we will open again the first two weekends of May, and we expect much nicer weather for you to shop and enjoy the spring garden.
Whether you’re a ferner or a native, you may be interested in the upcoming fern meeting….aka the Next Generation Pteridological Conference, scheduled to start at the National Museum of Natural History in Washington DC on June 1. If you’ve got a fern “jones,” consider joining us for the Smithsonian’s fern conference. Not only will you enjoy fern presentations, but you’ll be able to talk spores, stipes, and croziers while enjoying cocktails in the nation’s capital. For more information visit http://botany.si.edu/sbs/.
A hot-button topic is invasive exotics and, like with any scientific topic, the best thing we can have is dissenting opinions. Those with an open mind will enjoy these recent eye-opening publications:
Sign Up for Close-Up Photography Workshop and Garden Walks
We have a number of educational events scheduled at Plant Delights this spring from classes to conventions and we’d love for you to join us. You’ll find our list of classes here, starting with our Close-Up Garden Photography workshop on Saturday May 2.
American Hosta Society National Convention in Raleigh June 18-20
In June, we welcome the American Hosta Society, as hosta lovers from around the world descend on the Raleigh area to share and learn about their favorite genus of plants.Plant Delights Nursery/Juniper Level Botanic Garden will welcome the group to dinner, tours, and shopping on June 18. We really hope you’ll be able to join us. Register to attend the events at americanhostasociety.org.
Let’s Stay Connected!
Until next month, connect and follow us and the cats on Facebook, Pinterest, and our blog, where you may sign up and follow our regular posts from the nursery and the botanic garden.
One of the reason we are so passionate about plant trialing is that we can avoid offering plants like this phlox. This is Purple Eye Flame phlox taken in our gardens this week, part of the Bar Series from the Netherlands. While many of the phlox from this “disease resistant” series are excellent, others leave a bit to be desired when it comes to things like mildew resistance. Often these plants perform well in the breeders’ climate, but not so well in other parts of the world. While it will never be possible to adequate trial all plants in each ecological region, more trials are always better than less.
We hope you’ve received your copy of the Fall 2014 Plant Delights Nursery catalog. Kudos to our graphic designer Shari Sasser at Sasser Studios for the catalog redesign and new look. Among other things, the fall catalog includes three new aucubas, six new crinum lilies, and twenty new fern offerings. These are a fraction of the many exciting new plants you’ll find either in the print version or online.

Sweden & Germany 2014 Expedition Log
We’ve finally finished the online version of Tony’s expedition log from his trip to Germany and Sweden this spring…lots of cool plants, great gardens, and amazing people. If you’d like to travel along, enjoy the trek here.
Main building at the Munich Botanical Garden
Last Open Nursery and Garden Days for 2014 are Sept. 19-21
Grasshopper on Hibiscus ‘Turn of the Century’
This weekend, we’re putting the wraps on our final open nursery and garden days for 2014, so we hope you can make the trip to Plant Delights Nursery and Juniper Level Botanic Garden to share the splendor of the fall gardens. Not only is there lots to see here in September, but our muscadine grape trials are ripe, so you can sample each variety while you’re here…or park your spouse under the grapevines to keep them from pestering you while you peruse the gardens and shop.
2015 Open Nursery and Garden Dates Winter 2015
February 27 – March 1
March 6 – 8
In most parts of the country, it’s a fabulous time to plant…everything except agaves, echinaceas, bananas, and elephant ears (from Zone 7b north). North of us, just don’t plant anything marginally hardy in your zone as your first frost approaches and, in climates where the ground freezes in winter, allow enough time to get the roots anchored to keep the plants from heaving out of the ground.
Four months ago, we posted photos of our new four seasons garden that we’d just installed near our retail greenhouses. This section of the garden is now 16 weeks old, so we’d love for you to see what it looks like now and see how much it’s grown…a great demonstration why good organic soil preparation is so important and how much plants will grow when they’re properly cared for.

Nursery Industry News
PDN kudos to Plant Delights customer Allen Lacy, the founder and chief weed puller at the new Linwood Arboretum. Allen received some great publicity recently in an article in the Philadelphia Inquirer that we’d like to share.
We were also glad to see a recent article about our friend, the late Logan Calhoun, that just appeared in the Dallas News. Logan was a Plant Delights customer who shared many special plants that we still offer today…fifteen years after his untimely death.
In other news from the nursery world, Q&Z Nursery of Rochelle, Illinois, a major wholesale hosta tissue culture lab, is closing its doors. Although very disappointing, I can’t say I’m surprised. Q&Z, which has operated for 22 years since splitting from its former retail division T&Z, chose its market niche to be a hosta liner supplier to small mom and pop backyard nurseries.
They did this by offering a huge selection of new hostas (over 400 of their own introductions), without much, if any, in-ground evaluation, introducing seemingly every mutation that they found in the lab. If they tissue cultured a variegated hosta and it mutated back green, they would name and introduce the plant, knowing these small nurseries were usually more interested in having new hosta names in their catalog than having the best new hostas. This business model cost them the business of larger, more discriminating retailers, especially because they rarely had good photography of mature clumps of their new introductions…the single most important factor in properly introducing a new plant. Still, a few of their hostas turned out to be good plants that had staying power, including Hosta ‘Diamond Tiara’, ‘Pineapple Upside-down Cake’, Hosta ‘Radiant Edger’, Hosta ‘Sugar and Cream’, Hosta ‘Sugar and Spice’, Hosta ‘Summer Breeze’, ‘Summer Lovin’, and Hosta ‘Victory’.
Hosta ‘Summer Lovin’
Once the economy tanked, it took many of the smaller nurseries with it, making it even more difficult for such a business model to be sustainable. The founder/owner, Mark Zilis, is one of the most knowledgeable folks in the hosta world, as witnessed by his landmark hosta book, The Hostapaedia, which you can currently still purchase on the Q&Z website.
We’d like to publicly thank Mark and his staff for their contributions to the world of hostas, and wish them the best in their future endeavors.
Garden Director Needed
In local news, one of our neighboring botanic gardens is in need of a new director. Dr. Peter White, director of the NC Botanical Garden, is stepping down to return to teaching and writing, so the garden is in need of a new director. Interested? If so, you can find out more here.
Wedding Anniversary Flowers
Hydrangea macrophylla ‘Yofloma’
Do you struggle with what to get that special gardener in your family? Consider giving a wedding anniversary flower. Not only are there designated precious stones to celebrate wedding anniversaries, but there are designated plants. The list below suggests what you might present plantwise.
We try to share important life events from the horticultural world, but here’s one we missed. Ken Durio, 84, founder and president of the infamous Louisiana Nursery passed away last fall on October 28. I say infamous because Louisiana Nursery, was always the topic of customer stories whenever plant people gathered to discuss their new acquisitions. From the 1960s through the 1990s, if you wanted a rare plant…especially a woody plant, there were few sources other than Louisiana Nursery of Opelousas, Louisiana.
Hemerocallis ‘August Flame’
While Louisiana Nursery listed virtually every plant you could imagine, to the tune of 5,000 listings in their prime, the quality of the plants you received, combined with the extravagant prices and their less than stellar customer service, made it a major frustration for most consumers. I’ll never forget ordering their $5 catalog in the late 1980s only to get a return note asking which of their 12 catalogs I wanted…at $5 each…the iris catalog, the hemerocallis catalog, the magnolia catalog, etc.
Ken Durio was an avid and knowledgeable plantsman who started Louisiana Nursery soon after graduating from LSU in 1950. Although it seems hard to imagine today, back in the 1950s and 1960s, Louisiana was one of the epicenters of plant exploration and introduction in the US.
By the 1980s, Ken Durio had developed a reputation as one of the most ornery and curmudgeonly nurserymen in the country, which is why, when I was asked to speak in Baton Rouge in 1996, I told them I would only come if they’d take me to meet the infamous Ken Durio. After trying to talk me out of it, they reluctantly relented and off we went. Despite many tales of people being run off the nursery for no apparent reason, I found Ken both welcoming, hospitable, and glad to chat plants. By this time, however, the nursery had become quite run down as sales had dramatically declined. Louisiana Nursery (no relation to the garden center, Louisiana Nursery.com) became a victim of the Internet, as gardeners were now able to find better quality plants cheaper and without so much hassle.
Iris unguicularis ‘Purple Snow’
No matter what you thought of their business, their plant collections and breeding efforts in groups like iris, daylilies, magnolias, and figs were truly remarkable. One of Ken’s surviving sons, Dalton, recently returned home to take care of his dad in the last stages of life and is currently trying to resurrect the nursery. Fingers crossed for a successful re-launch. You can watch his progress at www.durionursery.biz.
Until next month, join us on the Plant Delights blog , where you can sign up and follow our regular posts from the nursery and garden.
As we mentioned in an earlier email, we experienced the perfect storm of events which impacted our order processing and shipping operations this spring. The combination of delayed ordering due to the long winter, a nearly universal demand for plants to be shipped in May, and the poorly-designed e-commerce system we purchased in December have created an operational and shipping nightmare. The entire company is working in crisis mode and we are burning the midnight oil to fulfill orders and work through the issues.
We know these delays are unacceptable to you and they are unacceptable to us as business owners. We appreciate your patience and your notes of support as we work to ship the orders that were delayed.
Despite seeming like spring has only just begun, we’re actually only a few weeks from the official start of summer. Rains have been steady so far this year, although our recent May rain of 5.17 inches was a bit more than we would have preferred for a single weather event. Fingers crossed for a great gardening summer in most parts of the country, although our thoughts are with those in the already drought stricken areas like California, Texas, and Oklahoma.
Spring open garden and nursery days were well attended and it was wonderful meeting so many folks, including visitors from as far away as California. It’s always great to put faces with the names that we’ve previously met only on social media. Because our growing season was two weeks later than normal, visitors were able to see different plants than they normally see in spring, including peak bloom on many of the early peonies. At least it was dry during open garden and nursery, which is always a relief.

Weathering the Winter in JLBG
In the last couple of weeks, the agaves here at Juniper Level B.G. have awoken from their winter slumber with seven species so far sending up flower spikes. It looks like we’ll be breaking out the tall ladders for some high-wire sexual liaisons before long. We didn’t get great seed set on last year’s century plant breeding, but the highlights of the successful crosses were hybrids of Agave victoriae-reginae and Agave americana ssp. protamericana which we expect will turn out to be quite interesting. Although only six months old, we can already tell they’re truly unique.
We continue to watch as plants in the garden recover from the severe winter. Most of the cycads (sago palms) we cut back have resprouted, with a few still to begin. So far, the only sure loss from that group was a several year old Dioon merolae. Most of our palms came through the winter okay, except for those in an out-lying low part of the garden, where damage to windmill palms was quite severe.
Many of the butia, or jelly palms, we thought survived have now declined to a brown pile of branches. We’re not giving up quite yet, as one Butia x Jubaea that we thought was a goner when the spear pulled (a term for the newly emerging leaves rotting so that they easily pull out of the top) has just begun to reflush.
Bananas have been slow to return for many customers, including the very hardy Musa basjoo. It seems that gardeners in colder zones who mulched their bananas have plants which are growing now. Perhaps this past winter will put a damper on the mail order nurseries who continue to list plants like Musa basjoo as hardy to Zone 4 and 5, (-20 to -30 degrees F), which is pure insanity.

We are grateful Tony had the opportunity to speak recently at the relatively new Paul J. Ciener Botanic Garden in Kernersville, NC. This small botanic garden is truly delightful, and the staff, including former JLBG curator Adrienne Roethling, have done a great job in the first phase of their development. We hope you’ll drop by if you’re heading through NC on Interstate 40.
Tony also spoke in Memphis last month, and then he headed into the Ozarks for some botanizing in northwest Arkansas. He had an amazing several days that resulted in finds like a stoloniferous form of Viola pedata, several trilliums he’d never seen before, and a new clematis species that’s still waiting to be named. We’ve posted some photos from the trip on our blog.
Zircon says “Don’t mess with my social media links!”
We both love to share our plant passion with you on the PDN blog and our social media sites. We originally posted only onFacebook, then Google+, Twitter, Pinterest and LinkedIn, so we created a PDN Blog as our main social media platform. Tony uses the blog to share his perspectives with you about the plant and gardening world as he sees it. The PDN blog, in turn, propagates his posts to Facebook, Google+, and Twitter and allows him to get back out in the garden and greenhouses where he finds meaningful content to share with you!
Anita manages the Juniper Level Botanic Garden website and the JLBG page at Facebook, along with the PDN and JLBG pages at Pinterest and LinkedIn. Thus far, the only issue we seem to have with social media is when the blog sends our posts to other social media sites, FB and Google+ remove the links to the plants, as well as some of the post. We have no ability to control or change this, and FB’s customer service is as responsive as asking a flat tire to change itself. Hopefully, one day we’ll discover a way to work around this challenge.
Suspending Web Ordering for Inventory June 17-18
Please note we will be closed to take plant inventory in the greenhouses on the above dates. This will require us to empty all shopping carts and suspend website ordering from 12:01am EDT on June 17 through 6:00pm EDT on June 18 in order to obtain accurate inventory numbers. We apologize for any inconvenience during inventory in June and October each year.
Taxonomy and Nomenclature
Longtime readers know Tony’s fascination with plant taxonomy and nomenclature. He always assumed plant naming and renaming had to do with science and taxonomy, but it seems that politics and nationalism are also at play. A recent example is the genus acacia, a member of the Mimosa family. It was determined in 2005 from DNA analysis that acacias from Africa and acacias from Australia were genetically different enough that they were not actually the same genus. Since the original type specimen, named by Linnaeus in 1773, was from Africa, the acacias in Australia were changed to racosperma.
What should have been cut and dried got hijacked when Australia protested, arguing that since they had so many more acacias than Africa (960 vs. 160), it would be too disruptive to change the Australian plants so Australia should get to keep the genus acacia, and a new type specimen (a replacement for the original African standard) should be declared as being from Australia. Follow me here…this would require the original African acacias to be renamed.
As it turned out, even the African acacias weren’t really all the same genus either, so they would then need to be divided anyway. This probably wouldn’t have garnered much in the way of horticultural headlines were it not for the fact that acacias are iconic cultural trees for both cultures. The result was a six-year heavyweight taxonomic and political rumble, the likes of which had never been seen before in the botanical world.
In 2005, the International Botanical Congress voted to officially give the name acacia to Australia. Africa vehemently protested, and accused the committee of stealing African Intellectual Property rights. In 2011, the International Botanical Congress, in a split decision, re-affirmed leaving Australia with the rights to acacia, and handing a still-steaming African delegation two new genera, vachellia (69 species) and senegalia (73 species), which taxonomist are still sorting out to this day. And you though taxonomy was boring!

Phlox paniculata ‘Purple Eyes’ with bees
In a recent discovery, scientists found bumblebees use electrical signals to determine which flowers have more nectar, allowing them to forage for pollen more efficiently. Bees build up positive electrical charges as they fly, which helps the pollen stick to them as they land on the flowers. Scientist found that this electrical charge is transferred to the flowers when they land to feed. Subsequent bees pick up on this electrical charge, telling the bee which flowers have already been foraged so they don’t waste their energy where little pollen will likely remain. This use of electrical signals had previously been documented in sharks, but not in insects. This fascinating research was first published in the February 21, 2013 issue of Nature magazine.
Industry mergers are back in the news this month as the 1,000,000 square foot Kentucky wholesaler Color Point (74th largest in the US) has signed a letter of intent to purchase the 3,500,000 million square foot Mid-American Growers of Illinois, which ranks number 13. Interestingly, both nurseries are owned by siblings…the two youngest sons of the famed Van Wingerden greenhouse family, who made their fortunes supplying plants to the mass market box stores.
In sad news from the gardening world, UK plantsman Adrian Bloom of Blooms of Bressingham shared the news that his wife of 48 years, Rosemary, has been diagnosed with advanced terminal cancer, falling ill after returning from a Swiss skiing trip in March. Adrian underwent prostate cancer treatment back in 2011. Please join us in sending thoughts and prayers to the Bloom family.
2014 Summer Open Nursery and Garden Days
Mark your calendar for July Summer Open Nursery and Garden Days. We’ll have the cooling mister running full blast to keep you cool while you shop for colorful and fragrant perennials for your summer garden. And of course, the greenhouses will be full of many cool plants, including echinaceas, salvias, phlox, cannas, dahlias, crinum lilies, and lots of unique ferns. JLBG is especially lush and green during the summer so come and walk the shady paths of the Woodland Garden, or cool off at the Grotto Waterfall Garden and Mystic Falls Garden. It’s always great to see you and meet you in person and to reunite with our long-time customers and friends.
Days: July 11-13 and July 18-20 Rain or Shine! Times: Fridays and Saturdays 8a-5p, Sundays 1-5p

Southeast Palm Society at PDN/JLNG on August 9th
Just a reminder that we will be hosting the summer meeting of the Southeast Palm Society at Plant Delights Nursery/Juniper Level Botanic Garden on Saturday August 9, 2014. You are welcome to attend but you will need to register in advance by July 1, 2014. You will find the details here.
Soothing Stress in the Garden
As crazy as things have been in the nursery, the botanic garden here at Juniper Level provides a paradoxically exciting calmness. As a stress reliever, as well as a passion, we spend as much evening and weekend time as possible in the gardens viewing the amazing plants and plant combinations through the lens of our cameras. We each see the garden differently, so Anita shares her photos on the JLBG Facebook page and her Google+ profile, and Tony shares his photos on the PDN blog.
In addition to the sensory beauty and serenity of gardens large or small, researchers worldwide have documented the positive and calming benefits to the human nervous system of spending time in the garden. So relax, refresh, and restore your natural state of balance and calm by spending time in your favorite garden spot.
The native Phlox ‘Minnie Pearl’ has been simply incredible in the garden this spring…in bloom for weeks already and still looking great. Phlox ‘Minnie Pearl’ is the first to flower of the upright phlox, and in our trials has never shown any sign of mildew. You’ve never grown a phlox like this.
It was great to finally see Phlox bifida in the wild, although we were shocked to see where it grew. We expected to find it on dry shale banks with Viola pedata, but instead found it growing in soggy wet seeps.
I’ve never encountered the likes of phlox like we saw in the Ozarks. Our first stop had three species of phlox growing together in a flood plain, Phlox paniculata, Phlox divaricata, and Phlox pilosa…which doesn’t look anything like Phlox pilosa I’ve seen in other regions. I appears that all the phlox integrade, as many plants there appeared to be hybrids among the many species. Truly, a fascinating conundrum.
It’s been quite a spring so far…very cool for much longer than usual…at least until early April. Plant emergence was far behind recent springs when, out of nowhere, temperatures rose in the 80s for ten days and the garden sprung to life. The subsequent late April temperature cool down, however, kept plant development about 1-2 weeks behind recent springs. Because of the sudden warm-up we experienced in early April, many smaller perennials will wilt despite the soil still being moist. As a gardener, this drives me a bit mad, but you have to realize the plants will adjust their stomatal openings (breathing holes) and be fine once they acclimate to the new temperature regimen, which usually only takes a couple of days.
One of the garden tasks that need attention in spring is assessing the amount of shade in your woodland garden. Spring is a great time to take stock of your woodland perennials, who will tell you if they are unhappy with the amount of light they are receiving. They won’t tell you via email or through their union reps, so you have to tune in and observe. If your plants seem to be going backwards in vigor or size…they used to flower but they no longer do so, you need to stop and figure out why. In almost all cases, spring ephemerals suffer a gradual decline in the woodland garden. Hostas that get smaller, trilliums that no longer flower and other woodland perennials that simply aren’t as vigorous as they once were are a sign of trouble. There are a number of potential culprits, from voles to a lack of summer moisture, but the cause that I see more than any other is an increase in the amount of shade.
Most shade plants need some light. In the case of spring ephemerals (plants that go through their entire life cycle in late winter/early spring), they need light during the short window of time before the trees develop their leaves. If you try growing spring ephemerals under evergreens, the results are usually not good. If all you have are evergreen trees and shrubs as an overstory, you can still help the situation by thinning out or removing selected limbs until you see rays of light reaching the plants below. Even plantings under deciduous trees can decline if the overstory isn’t selectively thinned on at least an annual basis. Now is a great time to monitor the perennials in your shade garden and determine which limbs need to be either removed or thinned, so get the hand pruners and pole saw ready. If you do this early enough in the year, plants can recover in only one season.
Athyrium (Lady Fern, Japanese Painted Fern) and Azalea ‘Redwing’
As most of you know, we are rapidly approaching our Spring Open House, May 3-5 and May 10-12. This a very special open house for us as it marks our 25th year in existence. Plant Delights and the gardens here at Juniper Level have come a long way since 1988, and we hope you will join us to celebrate this very special occasion. All of this would never have been possible without your tremendous support and for that, we can’t thank you enough. The dates for this and future open nursery and garden dates can be found at here.
The gardens here at Juniper Level look amazing thanks to garden curator, Todd Wiegardt, and his amazing staff and volunteers. I’m writing this from the garden patio where the evening aromas are in stronger than a Willie Nelson tour bus…from phlox to michellias (banana shrubs), to chionanthus and amorphophallus…there’s an aroma for everyone. Although the garden is perfumed all day, many of the best fragrances occur in late afternoon, so schedule your visit accordingly. If you’re attending open house for the first time, plan to be a bit overwhelmed. With over 20,000 different plants in the garden, it’s impossible to even begin to see everything in one trip. Heck, even I find new plants every day that I’ve forgotten. Our horticulture staff is stationed throughout the garden and nursery to answer any of your gardening questions, so don’t hesitate to ask anything that comes to mind as you stroll through the acres of gardens.
We also still have some room in our close-up photography class which takes place during the first Saturday of our open house. We are fortunate to have Josh Taylor, of Maryland, who also teaches photography at the Smithsonian, here to lead the class. You can sign up online here.
Strangely, we also have room remaining in our June propagation class for the first time in over 20 years. Again, don’t hesitate if you’d like one of the last spots.
Spring has been too busy for much traveling, but a recent 4-talk speaking trip through Tennessee, Virginia, and North Carolina did provide a bit of time for some spring botanizing. The highlight of the trip was the chance to see the recently discovered and soon-to-be named Trillium tennesseense….see the image we posted on the Trillium facebook page. Lots of other gems along the way, too numerous to mention here.
In the “in case you missed it file” this month, scientists have discovered that some plant nectar comes laced with caffeine, which enhances the Pavlovian response of garden pollinators. A bevy of bees in your garden may be, in fact, more like a line of latte-lovers standing in line at Starbucks than we ever realized. This adds to the stack of mounting evidence of how plants manipulate animals for mutual benefit. Although this relationship has been know for years using nectar sugars, this is a first for plants resorting to psychoactive drugs to lure suitors. These results come from honeybee expert, Geraldine Wright, of England’s Newcastle University, as an offshoot of her research to study human abused drugs.

Nursery News and Happenin’s
A recent shocker in the horticulture world was the fatal heart attack of Glasshouse Works co-founder, Tom Winn, age 67, on March 8. Tom is survived by his long-time partner, Ken Frieling. In 1985, Tom and Ken created one of the world’s finest sources of rare plants…primarily tropicals. Around 1990, when we were getting Plant Delights started, Glasshouse Works was one of my favorite places to visit, both to acquire plants, and also to learn about the mail order nursery business. Their display gardens were small, but packed with an incredible array of rare plants which served as an inspiration for our own gardens at Plant Delights. Tom was the front man for the nursery while Ken worked behind the scenes, so I know his life will be completely turned upside down. Our thoughts are with Ken and he continues to manage the nursery and deal with his loss. You can share a memory, a note of condolence or sign the online register book.
I also just heard from Jacque Wrinkle, that her husband, Guy Wrinkle, passed away April 20. Almost all collectors of cycads, caudiciforms (plants with swollen bases), or unusual bulbs have heard of or dealt with Guy and his mail order nursery, Guy Wrinkle’s Rare Exotics in Vista, California. I purchased my Trachycarpus takil from Guy in the mid-1990s and recently found it to be one of the few true Trachycarpus takil on the entire East Coast. We would later trade variegated agaves even before we finally met in person at the fall 2009 Agave summit in California. Guy retired from his career a biology professor in fall 2007 to devote more time to his love of plants.Unfortunately, he was diagnosed in 2009 with brain cancer, a condition he battled successfully until a new, more aggressive cancer recently proved too much to overcome. You can find one of Guy’s many articles online at Rare Exotics. Our thoughts are with his wife Jacque during this difficult time.
We recently also mourned the death of NC Botanical Garden founding director (1961-1986), Dr. Ritchie Bell, at the ripe age of 91. I was fortunate to have known Ritchie since the mid-1970s when he was a lone voice for the growing and propagating of native plants. I was greatly influenced by Ritchie’s philosophy of “Conservation through Propagation” which, unfortunately has now been largely abandoned by the garden he founded. Ritchie was also known as the author of several fabulous books; “Manual of the Vascular Flora of the Carolinas” (1968, co-authored with Albert Radford and Harry Ahles), “Wildflowers of North Carolina” (1968, co-authored with William Justice), “Florida Wild Flowers and Roadside Plants” (1980, co-authored with Bryan Taylor), “Fall Color and Woodland Harvests of the Eastern Forests” (1990, co-authored with his wife Anne Lindsey Bell) and “Fall Color Finder” (1991, co-authored with Anne Lindsey Bell). Ritchie was honored with a number of awards including the Silver Seal Award from the National Council of Garden Clubs and the Distinguished Alumnus Award from the University of North Carolina. Job well done, my friend!
I inexplicably missed the passing of our fern friend, Barbara Joe Hoshizaki, who passed away last June 24 at the age of 83. Barbara retired from the fern world a few years ago, due to aging and cognitive issues.Barbara Joe spent 28 years teaching biology at California City College when she wasn’t working in her wonderful home garden. She was a tireless promoter of ferns and served as President of the American Fern Society, President of the Southern California Horticultural Institute, and was a member of a number of other organizations. Barbara is best known for her book, “The Fern Grower’s Manual” (1975), and an expanded 2 edition with Robbin Moran (2001). Barbara was extremely helpful in identifying many of our ferns from our overseas expeditions, and we owe her a huge dept of gratitude. Barbara is survived by her husband, Takashi; two children, Carol (George Brooks) and Jon (Madeleine Takii), and other family members. The family requests that donations be made to the Organization for Tropical Studies, Box 90630, Duke University, Durham, NC 27708‑0630, “OTS in Memory of Barbara Hoshizaki.”
My final farewell today is to a group…the International Bulb Society. The 80-year-old International Bulb Society, which has long been an incredible resource to bulb lovers around the world, has decided to fold at the end of 2013. The society’s problems began over a decade earlier, when a series of ego-driven personality conflicts caused many of the members to drop out and join the recently-formed Pacific Bulb Society. Despite the fact that most new members didn’t live anywhere near the Pacific Ocean, the new group offered a more user-friendly format with far less drama while making sharing rare plants at low cost a key principle…the antithesis of IBS. I am truly sad to see IBS go as it brought together so many wonderful experts from around the world, and if you could afford the plant prices, it was a place to acquire the rarest of the rare bulbs. Who knows…if you believe in the afterlife, perhaps there will one day be a reincarnation of this wonderful group.
Until next month, we’ll keep posting plant photos from the garden and sharing all sorts of cool things from the world of horticulture on our Facebook Page.
Greetings from Plant Delights! We hope everyone has made it through another summer garden season in good shape. We’re wrapping up the open houses for 2012 with our final three days, Friday through Sunday this weekend. If you’re in the area, we sure hope you’ll join us. It’s been great to meet so many of our nearly 7,000 Facebook fans and friends in person at open house…thanks so much for taking time to follow our plant postings.
As we inch closer to the autumnal equinox, temperatures have begun to fall, which marks a resurgence of many plants that hibernated during the dog days of summer. Dahlias are like many plants that live for fall, and many of us cut our dahlias to the ground in late August so the fall flush will be look fresh and new. Perennial salvias such as the woody-stemmed Salvia greggiis put on their best floral show of the year in autumn when they flower nonstop for several months. Other salvia species like Salvia leucantha, and my personal favorite, the Salvia leucantha hybrid Salvia ‘Phyllis Fancy’, only flower in fall. Salvia ‘Phyllis Fancy’ is a Barry Bonds-sized steroidal monster, producing a 7′ tall x 8′ wide specimen in only 12 months.
What an amazing year this has been for butterflies in the garden…certainly, the best that I remember in over a decade. While butterflies were in abundance, Japanese beetles were nowhere to be found this year…not that we have much trouble with them anyway since we try to keep stressed plants out of our garden. Remember that most garden insects have cyclical population spikes, so don’t get too excited when a pest leaves or a new pest arrives.
One insect that made an appearance in our area starting a couple of years ago was the Genista caterpillar (Uresiphita reversalis). Baptisias have long been considered insect resistant since their leaves contain chemicals that repel most insects. Unfortunately, Genista caterpillars are immune to these leaf toxins. To make matters worse, the caterpillars have chemicals in their bodies that make them immune to most caterpillar predators…ain’t that just grand. While the Genista caterpillar is native to southern and central US, they have not been seen this far east until the last few years.
The unattractive nocturnal moths lay their eggs in spring, which subsequently hatch and the Genista caterpillar larvae begin feeding on the tender new baptisia plant growth. The larvae work fast and can completely strip the foliage of a mature baptisia in a few days…fortunately, this shouldn’t cause permanent damage to the plant. The larvae have 5 stages before they pupate for overwintering. Since the moths are quite prolific, they can actually lay several generations of eggs each year, so you’ll need to monitor your baptisias all summer. When the caterpillars are young they can be easily killed with organic BT (Bacillus thuringensis) products. Spinosad, a biological insecticide composed of Saccharopolyspora spinosa bacteria from crushed sugar cane, has also shown good effectiveness.
While I never expected to commit to writing another regular column other than our monthly e-newsletter, I recently had my arm twisted thanks to one of those once in a lifetime opportunities…the recent launch of Walter Magazine. The name may sound strange for those of you outside North Carolina, but our city of Raleigh, was named after Sir Walter Raleigh, a 16th century English flamboyant dressing explorer/spy. While writing a plant feature column for my hometown magazine was a great oppurtunity, this is also my first time to pair with former New York Times freelance botanical illustrator, the amazing Ippy Patterson.
I can’t believe I’m actually promoting a shrub pruning demonstration, but this isn’t just any shrub pruning. One of my favorite people, topiary artist Pearl Fryar, is coming to Raleigh for an artistic demonstration at NCSU’s new Gregg Art Gallery at 1903 Hillsborough Street. The date is Sunday October 28, from noon until 4pm. This free event is a gathering of artists and musicians…refreshments will be provided. If you’ve seen the movie, “A Man Named Pearl”.
and want to meet this amazing man in person, don’t miss the event.
In the latest news from the nursery world, the 65-year-old Klupengers of Oregon is closing their doors. Klupengers is a 320 acre wholesaler specializing in japanese maples, rhododendrons and azaleas. Klupengers Nursery had sold out once before, but wound up buying the nursery back in 2010 hoping to outlast the downturn, which didn’t work out so well. Everything including land is currently being liquidated, unless someone wants to buy the entire operation.
It was also time for more consolidation in the green industry this month as the world famous, 3rd generation Ecke Ranch was purchased by Agribio International. For those of you not in the horticulture industry, the majority of the poinsettias you buy at Christmas were introduced by the 1000-employee Ecke Ranch of California. Ecke also has a large geranium breeding program. It appears for now the company will remain intact other than a change in ownership.
Agribio Holding B.V. is a Dutch investment firm, specializing in purchasing plant breeding businesses. It recently acquired Barberet and Blanc, a carnation breeder in Spain; Bartels Stek, an aster, solidago, and phlox breeder in Holland; Fides, a bedding and potted plant breeder in Holland; Oro Farms, a production facility in Guatemala; Japan Agribio, a breeder of bedding and potted plants in Japan; and Lex+, a rose breeder in Holland. The acquisition of Ecke makes Agribio one of the largest producers of cutting-produced ornamentals in the world.
It’s with sadness that I report Ohio hosta breeder and nurseryman Bob Kuk, of Kuk’s Forest Nursery passed away on August 14 after a short illness. During his lifetime, Bob developed and introduced over 50 hostas including Hosta ‘Bizarre’, ‘Emerald Necklace’, ‘Golden Empress’, ‘Queen Josephine’, and ‘Unforgettable’. In 2011, Bob was awarded the Distinguished Hybridizer Award by the American Hosta Society for his body of work. Our thoughts go out to both Bob’s hosta family and friends. < href=”http://www.americanhostasociety.org/2011FisherSpeech.html”>Learn more about Bob.
I recently got an email from Dr. Charlie Keith, whose Chapel Hill, NC Arboretum I’ve written about several times. Charlie is turning 80 soon, and has come to the realization that he hasn’t been able to raise adequate funds to preserve the arboretum as he had hoped. Consequently, he’s looking to sell the arboretum property which houses one of the largest woody plant collections in the country. Charlie will be hosting an open house on October 21, from 1-5pm, with plantsmen Mark Weathington of the JC Raulston Arboretum and author Tom Krenitsky as tour guides. The arboretum is located at 2131 Marion’s Ford, Chapel Hill (for more information). If you know of anyone interested in purchasing the 80 acre property, please get in touch with Charlie, as his collection is simply too important to lose.
From the medical world, recent research from The University of Sichuan, published in “Current Chemical Biology” (Volume 3, 2009), has shown the common snowdrop, Galanthus nivalis, has great potential as an anti-fungal, anti-viral (including HIV), and anti-tumor agent for several cancers, including breast cancer. The report also studied the significant anti-tumor lignin activities of other related monocots including Aspidistra elatior (cast iron plant), Polygonatum odoratum and P. cyrtonema (Solomon’s seal), Narcissus pseudonarcissus (daffodil), Ophiopogon japonicus (mondo grass), Typhonium divaricatum (dwarf voodoo lily), and Viscum sp. (mistletoe).
Other common ornamental plants with very specific anti-HIV activity include Lycoris radiata (surprise lilies), Polygonatum multiflorum and P. cyrtonema (Solomon’s seal), Hippeastrum hybrids (amaryllis), Cymbidium hybrids (orchids), and Narcissus pseudonarcissus (daffodil). This is just another reason that the federal government should be doing much more to make plant exploration and importation easier and reverse the current trend toward plant exclusion and making plant importation exceedingly difficult.
Enjoy, and until the next newsletter, we’ll keep in touch on Facebook!
