For many, fall is the best time of year to garden. The heat of summer has finally broken and the crisp autumn air is a delight to work in. Fall perennials take over for the summer flowers and keep the garden showy as the days get shorter.
Zephyranthes has the common name rain lily for a good reason…it has the charming habit of sending up new blooms after a summer rain (it would make an excellent rain garden plant). Zephyranthes (rain lilies) are small perennial bulbs that need to be sited in the front of the border, or in a rock garden to be appreciated.
With an abundance of days in the mid 90’s in July, August has started with an abundance of rain, from hurricane Isaias to afternoon thunderstorms. And the rain lilies are loving it! Here are some of our rain lily collection in our outdoor production beds. Let us know which ones appeal to you and we will try to get them in future catalog!
Variegated plants have part of the normal green portion of the plant leaf being replaced by white, cream, yellow, or occasionally other colors. How cool is that!
As a design element, variegated plants are often used as the center of attention or as a focal point in the landscape to lighten up a normally dark space.
Plants with bold variegation seem to scream for attention in the garden, hence their use as accent plants. As with all brightly variegated plants, they show off best when contrasted against a dark background. Whether planted against a mostly green hedge, or a larger backdrop of deciduous trees, some background is needed to properly display variegated trees, shrubs and perennials.
Opuntia is a rather large genus of cacti, containing some 200 or more species native to the deserts of the Americas. Opuntia are amazingly adaptable and can be found native in almost every US state and Canada. Plant Delights Nursery at Juniper Level Botanic Garden has a large collection of opuntia with over 300 unique clones.
Many of our opuntia clumps have gotten quite large over the years and are in need of dividing. We will be offering pads of select clones to give away (pick up only) during our 2020 Summer Open Nursery & Garden Days. What a great time to start an opuntia collection!
Opuntia species have a distinctive look, with flat pads, beautiful, large flowers and fig-sized, maroon fruits. Both the fruits and the young pads are edible provided that you carefully remove all of the thorns and hairs.
Add summer color to your patio, pool or deck with perennial container gardens. There are many great summer blooming perennials that work well in containers and provide a pop of color even if you have limited garden space to plant. There are many types of containers that can be used and left outside year round. The containers shown here are a resin material that is weather resistant and come in an array of sizes and colors that can fit into any decor. These containers may need to have holes drilled into the bottom for drainage, and many have punch-out holes. They are light-weight and are easily moved even after planting. There are also ceramic and concrete planters that are frost proof and available in every conceivable shape, color and size.
Some colorful and long blooming summer perennials you may want to consider for your containers include colocasia, perennial hibiscus, cannas, verbena, flowering maple, dahlias, monarda (bee balm), and daylilies. Other evergreen and variegated perennials can be grown in containers as well, such as aspidistra (cast iron plants), agave, mangave, and cacti. Hostas also make great container plants for the shady spot on your patio.
It is important to consider plant hardiness when creating your planter. Remember that since the plants roots are above ground and not insulated, they will be subjected to colder air temperatures during the winter. Depending on the length and severity of the winter, some plants may be just fine through the winter, or your container garden may benefit by being brought into the garage, sun room or porch area during the winter, or situated in a micro-climate, like next to a south facing brick or stone foundation.
This is the week that we had expected to welcome hundreds of participants from all over the world to the 2020 Southeastern Plant Symposium in Raleigh, NC, but world events had other plans. So, we shifted gears and put together a replacement on-line symposium that will take place this Friday June 12 from 10am-3pm. This is a fund raiser for both the J.C. Raulston Arboretum, and for the Juniper Level Botanic Garden endowment, so we hope you can join us safely on-line. If you sign up, but aren’t available on Friday for the live event, you will also receive a private link, so you can also watch the symposium later.
The stellar lineup for the 2020 rapid-fire on-line symposium for plant nerds includes:
Dan Hinkley – World renown plant explorer and founder of Heronswood Gardens/and Nursery. Dan will speak on A Morning Walk-through of Gardens of Windcliff.
Nick Macer – World renown plant explorer and owner of Pan-Global Plants in the UK will speak on Things That Turn Me on—Confessions of a Plant Freak
Kelly Dodson/Sue Miliken – World renown plant explorers and owners of Far Reaches Farm and Conservancy. They will speak on Plantdemic in the Far Reaches.
Jimmy Turner – World renown plantsman, Director of Red Butte Botanical Gardens, and former Director of Horticulture of the Dallas Arboretum and later the Director of Horticulture for the Royal Botanic Gardens, Sydney. Jimmy will speak on The Land of Ahs.
John Cho – Retired University of Hawaii professor and breeder of the Royal Hawaiian series of colocasia (elephant ears). John was world renown for his breeding work with food taro before he turned his attention on revolutionizing the ornamental elephant ear offerings. John will speak on Breeding of the Beautiful Royal Hawaiian Collection of Colocasia.

When we finally discovered that sea kale (Crambe maritima) is indeed growable in our hot, humid climate, we’ve planted it all around. It’s also been rewarding that people have actually purchased it to try for themselves. Frankly, I’d grow sea kale for the ornamental value alone…a perennial with blue waxy foliage and an incredible show of white flowers in spring! Then, there’s the edibility, both cooked and raw. Also, for us, unlike other cabbages and kale, it has been virtually untouched by the pesky cabbage loopers.
Here is a photo of sea kale in our crevice garden this April, growing in a soil mix that’s 50% gravel, with no summer irrigation. Read my lips, I mean text…full baking sun and no irrigation after establishment. We recommend you never let your plants read the repetitive on-line sites that all tout that it only grows in cool, moist, climates…hooey!
Amsonia (aka: bluestar) are one of the best temperate genera (18 species) of blue-flowered perennials for the spring garden. We’ve offered quite a few different species and selections through the years, rotating them in and out as propagation successes allow and as sales dictate. All but two of the species, (Amsonia orientalis from Europe and Amsonia elliptica from Asia) are North American natives. Most are extremely drought tolerant, while others like Amsonia rigida and Amsonia tabernaemontana can tolerate very wet soils.
Amsonia montana is a commonly grown plant of mystery, having just appeared in horticulture, but never been documented from a wild population. A few of the amsonia species have flowers so pale blue that they appear white in the garden with only a hint of blue on the flower corolla. Amsonia are quite promiscuous in the garden, so if you grow more than one species nearby, you will have hybrids from seed. We hope you’ll explore this amazing genus of perennials.
We are saddened to announce the passing (May 12) of one of our closest friends, plantsman Alan Galloway, age 60. In addition to serving as an adjunct researcher for Juniper Level Botanic Garden, Alan was a close friend and neighbor, living less than two minutes from the garden/nursery.
Alan was a native North Carolinian, who grew up on a farm in Brunswick County, NC, where he developed his love for plants and the natural world. After graduating from UNC-Wilmington with a Computer Science degree, and working for his alma mater for two years, he made the move two hours west to Raleigh. There, Alan worked at NC State University in IT administration and management for 30 years, until retiring in Fall 2018 as Director of IT Services.
Starting in 1999, Alan would save up his vacation time from his day job at NC State, and spend 3-4 weeks each fall, trekking through remote regions of the world where he felt there were still undiscovered aroid species to find, document, and get into cultivation. From 1999 to 2018, he managed 21 botanical expeditions around the world, that included the countries/regions of Cambodia, Crete, Hong Kong, Laos, Mallorca, Philippines, Thailand, and Vietnam.
Alan routinely risked life and limb on his travels, whether it was getting attacked by a pit viper in Thailand, barely missing a land mine in Cambodia, or tumbling down a mountain and almost losing a leg in Laos.
I had the pleasure of botanizing in Crete, Thailand and Vietnam with Alan, which was an amazing experience, although not for the faint of heart. Alan was a tireless force of nature, but was not one to suffer what he viewed as stupidity or laziness. Although he was very respectful of people from all walks of life, he also regularly burned bridges to those whom he found incapable of meeting his meticulously high standards.
Alan was botanically self-taught, but his obsessive compulsion led him to become one of the worlds’ leading experts on tuberous aroids, specializing in the genera Amorphophallus and Typhonium. To date Alan is credited with the discovery of 30 new plant species (see list below). He was working on describing several more plants from his travels at the time of his death.
Not only did Alan’s botanical expeditions result in new species, but also new horticultural cultivars of known species. Two of the most popular of these were Leucocasia (Colocasia) ‘Thailand Giant’ (with Petra Schmidt), and L. ‘Laosy Giant’.
As a scientist, Alan was both meticulous and obsessive. It wasn’t enough for him to observe a new plant in the field, but he felt he could learn far more growing it in cultivation. He would often work through the night in his home research greenhouse studying plants and making crosses, so he could observe seed set and determine other close relatives.
Alan was overly generous with his knowledge, believing that sharing was necessary for the benefit of both current and future generations of plant scientists. Without his expert understanding of crossbreeding tuberous aroids, we would never have been able to have such incredible success in our own aroid breeding program. Seedlings from his crosses were then grown out and observed, often resulting in a number of special clonal selections.
After his tuberous aroids went dormant each year, all tubers were lifted from their containers, inventoried, and carefully cleaned for photography and further study. Visiting his greenhouse during tuber season was quite extraordinary.
In his amazing Raleigh home garden and greenhouse, Alan maintained the world’s largest species collection of Amorphophallus and Typhonium, including 2 plants named in his honor; Amorphophallus gallowayi and Typhonium gallowayi. Alan’s discoveries are now grown in the finest botanical gardens and aroid research collections around the world.
After returning from what proved to be his last expedition in Fall 2018, he suffered from a loss of energy, which he attributed to picking up a parasite on the trip. It took almost eight months for area doctors to finally diagnose his malaise as terminal late stage bone cancer, during which time Alan had already made plans and purchased tickets for his next expedition. I should add that he made his travel plans after being run over by a texting pickup truck driver, and drug under the truck for 100 feet through the parking lot of the nearby Lowes Home Improvement, which ruined his kidney function.
Alan was certain, albeit too late, that his cancer came from a lifetime addiction to cigarettes, which he was never able to overcome. Over the last 18 months, it’s been difficult for those of us who knew Alan to watch him lose the vitality and unparalleled work ethic that had been his trademark. Despite his loss of physical ability, his trademark independent/stubborn nature would still not allow him to even accept help driving himself to chemo infusions and blood transfusions, which he did until he passed away. Alan was also never one to complain or bemoan his circumstances, only continuing to accomplish as much as possible in the time he had remaining.
After the initial shock of his diagnosis, Alan systematically began distributing massive amounts of his ex-situ conservation aroid collection to gardens and gardeners around the world, since he also believed that sharing is the most effective means of plant conservation.
One of his hybrids that Alan had shared and asked us to keep a special eye on was his cross of Amorphophallus kachinensis x konjac. We talked with him last week and shared that the first flower was almost open, and he was so excited to see his baby for the first time, but by the time it opened early this week, it was too late. So, here is the photo of his new cross, seen for the first time that would have made him so proud.

Not only has Alan been a good friend for over 30 years, but he has been extremely generous in sharing with us at PDN/JLBG. Over 1500 plant specimens in our collection came directly from Alan. It still seems surreal that we have lost such a vibrant soul that has been so important to expanding our body of knowledge about the botanical/horticultural world. Farewell, my friend…you will be sorely missed.
We will be coordinating with his niece April and her husband Mark to plan a celebration of Alan’s life, which will be held here at PDN/JLBG at a future date, which we will announce when it is set.
Ok, the spelling of “Susanna” is slightly different, but don’t let that deter you from growing one of the greatest groundcover clematis that we’ve ever grown. Yes, that’s right…no mailbox post or staking required. We’ve been growing this amazing, compact clematis as a groundcover for years and it is truly superb. Here it is in the garden this spring, but it will also continue to flower into summer. What’s not to love about Cezanne!
