Gardeners' Notes:


On Apr 16, 2012, brwnails from Riverside, IL wrote:

Obtained from the now gone Roslyn Nursery mail order 2007. Plants are about 4ft now by 3ft, upright oval habit. Little to no die back, growth slow and steady in semi shaded spot. Delicate looking shrub, dainty flowers. Recommend planting in the perennial border or native garden. Really happy with the plants.

I found this shrub a few years ago blooming on a stream bank. The owner of the property thought it was silverbells but when ( at a later time) I showed him a silverbell tree he changed his mind.
I think this shrub makes a beatiful addtion to a wet area or a streamedge if you have one.

This is a lovely, subtle native snowbell, particularly the northern form which is sometimes listed as the "Kankakee" form. Somewhat resembling Styrax japonicus in foliage, this plant is much more shrubby. The flowers, though small, are numerous and extremely beautiful. They again resemble Styrax japonicus except that the petals reflex in a most delicate manner.
