Trochodendron arailoides

Driving the Wheel Tree Renaissance

One of our favorite evergreen trees is the little-known, Trochodendron aralioides. I first met the wheel tree at the JC Raulston Arboretum back in the 1980s, quickly falling in love with the fascinating foliage, which is arranged at the branch tips, like spokes on a wheel. As the curator of the Arboretum’s Lath House, I

Zingiber mioga 'Lushan Gold'

Magnificent Mioga

This year, we introduced an amazing new Chinese collection of the shade-loving Mioga ginger, that we named Zingiber mioga ‘Lushan Gold’, from an Atlanta Botanical Garden expedition. It’s amazing, first, in that it clumps, instead or runs like many forms of the species. We grew quite a few from seed, looking for any that might

Microsorum buergerianum 'Datun'

Evergreen Fern Mat

We just snapped this photo of one of our more amazing fern introductions, Microsorum buergerianum ‘Datun’. This six year-old clump is from our 2008 spore collection of this fabulous mat forming, epiphytic fern from north of Taipei, Taiwan. Although the foliage burnt back at 11 degrees F, it re-flushed quickly the following spring. Hardiness Zone

Arundinella hirta 'Cheju-Do'

Cheju Charmer

A few years ago, I was fascinated to see a catalog listing for a new ornamental grass that I didn’t know, Calamagrostis ‘Cheju-Do’. This struck my eye because calamagrostis are great ornamental specimens, and in 1997, I had the opportunity to botanize Korea’s southern island, Cheju. We subsequently acquired a specimen, which prospered for us,

Liatris tenuifolia 'Jasper'

Slender-leaf Blazing Star

I first met the rarely-cultivated slender-leaf blazing star on a 2022 staff expedition with Patrick McMillan and Zac Hill, to Jasper County, SC. Here, Liatris tenuifolia grew throughout the dry, sandy habitat in between gopher tortoise mounds. The native range of this species, stretches from SC southwest to Mississippi. Our seeds from the expedition sprouted,

Actaea pachypoda

Hey Doll, love those Eyes

Looking lovely in the garden now is the woodland perennial, Actaea pachypoda, commonly known as doll’s eyes. Most of the commercial material available in the trade comes from much colder climates, and will not survive our summers. It has a huge native range from Canada south to Louisiana, so it’s surprising that introductions of heat

Eucomis 'Sparkling Burgundy'

A Toast with Sparkling Burgundy in the Garden

Looking great in the garden this week is Eucomis comosa ‘Sparkling Burgundy’, seen here with a couple of North American natives, Thuja occidentalis ‘Concessarini, and Physocarpus opulifolius ‘Summer Wine’. Eucomis ‘Sparkling Burgundy’ was one of our first Plant Delights/JLBG introductions in 1997 and since that time we have introduced over 1,440 new plant species, cultivars
