One of the first shrubs we planted at JLBG in the late 1980s was the giant snowball bush, Viburnum macrocephalum sterile form. Today, this amazing selection of the Chinese native species, tops out at 25′ tall. In April each year, it puts on a truly indescribable show, as you can see from our new April […]

Several years ago, we grew seed of Dianthus anatolicus, native from Tibet to Turkey, and while all were interesting and deliciously fragrant, one, which we named Dianthus ‘Lunatic Fringe’ stood out from the rest for its exceptional floral show, and heat/humidity tolerance. Our original plant, pictured below, is now almost five years old and still
Looking quite dazzling in mid-April is our specimen of the Chinese fringe tree, Chionanthus retusus ‘China Snow’. The incredible masses of white flowers perfume quite an area during the flowering period. This is a particularly heavy-flowering selection from the late nurseryman, Don Shadow. Mature size is 30′ tall x 30′ wide, with a winter hardiness
This week marked our annual flowering of the endangered African aroid, Pseudohydrosme gabunensis ‘Stained Glass’, which we first flowered in 2021. Kew Gardens recently posted that they just flowered it for the first time ever in the UK. This tropical African rain forest genus is comprised of only three species, all from the countries of
Is anyone other than us growing, the Japanese woodland perennial, Ainsliaea cordifolia? This odd member of the aster family has strikingly patterned foliage, but for us, has been painfully slow to grow. The plant below is all we have after 18 years of cultivation of a plant we purchased originally from Barry Yinger’s Asiatica Nursery.

We’re preparing for another crazy year of century plant breeding, with fourteen agaves in spike so far. After flowering 34 clones over the last two years, we expected less this year, but now, that doesn’t appear to be the case. From the initial spike appearance to the first flowers opening is generally 6-7 weeks, so
Early April is peak time at JLBG for Ajuga flowering, commonly known as bugleweed. We think these amazing new cultivars are a great solution to reducing the need for mulch in sun to part sun landscaped areas. Some of the new colored leaf cultivars are even more spectacular when in flower…below are a few.

Looking lovely in the garden this week is the amazing native (Pennsylvania south to Georgia) Fraser’s sedge, Carex fraseriana. This sedge is so odd, that it spent much of its life, relagated to it’s own, lonely genus, Cymophyllus. We failed with this countless times, before we planted one in between rocks, which seems to have
I’m just back from speaking to a couple of North American Rock Garden Society Chapters in Massachusetts, an area I hadn’t visited in over two decades. My journey began at the Berkshire Botanic Gardens in Stockbridge, a venue I last spoke at in 1999. Over 50 folks showed up on a cold, drizzly day, as

On a 2019 botanical expedition to Montgomery County, NC, our staff (Zac and Jeremy) discovered this never before documented natural hybrid between Dentaria dissecta (Cardamine dissecta) and Dentaria laciniata (Cardamine contactenata). We’ve christened two clones from the population, Dentaria x lacinisecta ‘Whitened Teeth’ (top) and Dentaria ‘Angel Hair’ (below). Now, we just need to have
