Hardy Agave for Your Garden

There are many agave that are hardy in our Zone 7b garden that many people would not think would live here. The key to successfully growing agaves is proper siting, planting, and culture. These are pictures taken this week of agaves in the garden. Join us May 4, 2019 at 2:00pm for our Gardening Unplugged garden chat on Hardy Agave for the Garden, during our Spring Open Nursery & Garden Days.

Spring Open Nursery & Garden is Just Around the Corner

It's hard to believe that spring open nursery and garden days is almost here. Spring is always a busy time of year and our nursery and garden staff have been working tirelessly making sure the gardens are in prime condition and our sales houses are brimming with beautiful plants. Take advantage of shopping our sales houses for many unique and rare perennials, many exclusively available at Plant Delights Nursery. We are offering nearly 20 varieties of Baptisia this year, more than you will find at most garden centers. Many are from our own breeding program at Juniper Level Botanic Garden and include two 2019 introductions you will find no where else. Join Tony, Friday, May 3 at 10am for a stroll through the gardens as he discusses baptisias, part of our Gardening Unplugged garden chat series. Baptisia Bletilla - Hardy Orchids The hardy orchids also look amazing this year, with seven different bletilla and over 30 varieties of ladyslippers and calanthe available, you are sure Read more [...]

Urbanite Crevice Garden

If you haven't been out lately, the last section of our crevice garden along the exit drive is nearly finished and being planted as we speak. Previous sections are starting to fill in nicely and really shining this spring. Be sure to visit during our upcoming 2019 Spring Open Nursery & Garden Days, May 3-5 & 10-12, and get inspiration for your own crevice or rock garden. Read more [...]

Seeds of Change

At Plant Delights Nursery and Juniper Level Botanic Garden we grow a number of our plants from seed. While many plants will come pretty true to type from seed, there is always the element of genetics and genetic diversity, just as in humans. We are always on the look out for these genetic variations and the next great garden worth plant. Below is a planting of 3 Alyssum argenteum that were grown from seed received from Jelitto Perennial Seed. All planted at the same time and same conditions, side by side, you can see the plant to the far left is already in flower, the middle plant is just starting to bud, and the far right is denser and more compact in its growth habit. Alyssum argenteum - Jelitto form Below is another seed grown crop of Alyssum saxatile 'Sulphureum' and you can see the variation of flower color from a creamy, buttery yellow to a bright golden yellow. So we are always excited about growing crops from seed and discovering the variations nature has in store. Alyssum Read more [...]

But, they don’t grow here

We have long admired the Aril iris, a group of dry-land species, mostly from Middle Eastern countries, which are renown for their ability to die quickly in wet, humid-summer climates.  Well, armed with our new crevice garden, we decided it was time to try our hand at these once more, focusing on what is known as Arilbred iris...aril species that have been crossed with more typical bearded iris. In our case, we focused on the 50/50 hybrids, which the vendor assured us would not have any chance in our climate. 

Despite our wettest year on record, here we are, 20 months after planting without a single loss. Here are a couple of photos from last spring, as we await the 2019 show (two center photos) just a few weeks away.  The crevice garden should look amazing for our Spring Open Nursery and Garden days...we hope you'll come visit. The lesson...don't believe anything you're told unless you verify it yourself.

Lies, Damn Lies, and Plant Labels

We just snapped this photo of Lemon Thread Cypress (Chamaecyparis pisifera 'Lemon Thread') in the gardens here at Juniper Level, and wanted to share since it illustrates our constant rants about trusting nurseries, plant tags, and websites to give accurate mature sizes. For a woody plant, our typical advice is to triple any size you are given. So, we wanted to see how that advice would work with the plant below.

Lemon Thread cypress was discovered in the mid 1980s as a sport at Oregon's Mitsch Nurseries, so it's a relative newcomer as plants go. Our 20 year old specimen is planted in compost-amended sandy loam without any chemical fertilizers ever. We should also add that we don't believe in shearing plants, which we find a waste of energy as well as a middle finger to natures's beauty. Our specimen now measures 25' tall x 15' wide.

We then searched the web for Lemon Thread Cypress and recorded the sizes from the top 30 sites that came up in Google...see notes below the photo.  Sizes Read more [...]

New Sterile Hellebores

We are rightly skeptical of great new plant claims, since so many new introductions fail to live up to the marketing hype, so we were cautiously optimistic when we planted our first trial plants of Helleborus x glandorfensis a couple of years ago.

These new, thought to be impossible hybrids of Helleborus niger x Helleborus x hybridus, have indeed lived up to the marketing hype. They are similar to the incredible Helleborus x iburgensis hybrids, which preceded them (crosses of Helleborus niger, hybridus, and lividus), but without Helleborus lividus, which produces the leaf veination, but reduces the flower size slightly.

The H. x glandorfensis hybrids (created by breeders in Glandorf, Germany) have dark, black green foliage, with flowers which are ridiculously large for a lenten rose.

Both the H. x glandorfensis and the x iburgensis hybrids have outfacing flowers and do not produce seed. You can't go wrong with any of these amazing hybrids for the winter garden!

What’s Growing On?

March 2019 Newsletter News from JLBG/PDN 2018 was a year of exceptional changes for us here at the gardens and nursery.  Our long-time nursery soil company was sold and the quality of the mix went to hell. Because many of our crops are challenging in containers, before we knew it, our plant losses in the nursery were well into the upper six figures. To say our nursery staff had to scramble is an understatement. After trialing our most difficult crops in a number of new potting soil mixes, is was an easy choice to make the switch to Pacific Organics. https://www.pacific-organics.com/Despite the name, Pacific Organics is a NC-based national company, who have a bigger footprint of users in the northeast US than here in NC, where cheap nursery soil is king. Unbenownst to us, the folks at Pacific Organics have worked closely with the world renowned soil researchers at NC State, so we know the quality of the research they use to formulate their mix.We take great pride in Read more [...]

New baby tucked away in plain view

Even though we're in the garden virtually everyday, there's so much to see that we often miss things that are right in front of us.  Case in point...a few weeks ago, our taxonomist, Zac Hill was walking though the woodland garden and noticed that our evergreen Solomon's Seal had been sexually frisky with another disporopsis species in a nearby clump. In the photo on the right is the daddy, Disporopsis pernyi, and on the left, the momma, Disporopsis undulata.  In the center is the baby...a hybrid between the two.

The hybrid clump was actually fairly large, so we'd missed the blessed event by several years. According to disporopsis guru, Dr. Aaron Floden of the Missouri Botanical Garden, this seems to be the first time that anyone has documented a hybrid between these two species, so we named our new baby Disporopsis 'Opsis Attract' and look forward to being able to share in a few years.

Winter Color Combo

Here’s a fun new winter color combo we tried in the garden that looks great now…Nothoscordum sellowianum (the insanely fragrant yellow winter-flowering bulb as a highlight for the purple-foliaged Yucca aloifolia ‘Magenta Magic’…pretty pleased with how this turned out.
