Stunning Townhouse

Lagerostroemia faurei ‘Townhouse’ is looking great at JLBG this summer. This compact selection was named by the late J.C. Raulston, in addition to the taller, narrower cultivar L. ‘Fantasy’. Townhouse crape myrtle is also highly prized for its dark cinnamon bark…the darkest of any crape myrtle we know. Our oldest specimen is now 35′ tall

The Thrilla of Cyrilla

If you’ve been following our blog for a while, you’ll remember we wrote about this amazing native shrub/small tree last summer. Well, it’s cyrilla time again in the gardens at JLBG, when every branch of this amazing semi-evergreen erupts with racemes of small white flowers, inviting all insects in the neighborhood to stop by for

Oldham’s Azalea

Few gardeners have probably grown the Taiwanese Rhododendron oldhamii, but this little-known species has become one of the most important azaleas in American horticulture. Here it is flowering in our garden in late spring. Then will be followed by a late summer/fall rebloom. Rhododendron oldhamii was named for British plant explorer Richard Oldham (1837-1864). Here’s

Ocoee Leatherflower

Clematis vinacea is a recently described species of non-vining clematis, published in 2013 by plantsman Aaron Floden. In the wild, it grows in a small region on the border of Eastern Tennessee/Northern Georgia. Closely allied to Clematis viorna/Clematis crispa, Clematis vinacea is a compact, non-climbing species. For us, it makes a sprawling mound to 18″

Staring into Starry Eyes

Nierembergia ‘Starry Eyes’ is looking particularly dazzling in the rock garden at JLBG. Starting to flower for us in late April, this incredible gem is from our 2002 botanical expedition to Argentina. I distinctly remember walking by as our friends from Yucca Do Nursery extracted a small piece of this nierembergia with only a single

David’s Tree

We’ll certainly remember 2022 for many reasons, but a highlight is the first flowering of our Davidia involucrata ‘Sonoma’. This incredible tree was named for French missionary and naturalist, Armand “Pere” David (1826-1900), who first discovered the tree in its native China. Like dogwoods, what we think of as flowers are actually bracts, the effect

Hi Jacks

Over the last few weeks, I’ve been working on a plant survey of a local woodland area of about 30 acres. The low, moist areas are filled with Arisaema triphyllum, (Jack-in-the-pulpit) which is quite common in our area. The first image is what is typical for the species. I’ve been studying patches of Jack-in-the-pulpit for
