‘Dark Horse’ is a compact, dwarf cultivar with deep purple leaves and abundant pink flowers. Spreading, dense, rounded shrub, with branches eventually arching to the ground.

Platanus x acerifolia is quite similar to P. occidentalis, but was originally advertised as being much more pest resistant. P. x acerifolia was quickly overplanted, and it is clear that pest resistance varies among hybrids, and can be quite poor. Pests that can severely affect this species include sycamore anthracnose, cankerstain, Botryosphaeria canker, leaf spot, […]
‘Viridis’ is a narrow columnar cultivar with bright green, twisted needles that emerge bright yellow-green in the spring. Withstands nearly any amount of pruning. Black vine weevil can be a problem, but this is rare. Newly planted yews do not perform well in poorly drained soils. Perhaps overused in the urban landscape. Can be severely […]

The Autumn Magic Black Chokeberry is known for its outstanding bright purple to red to orange fall color, compact form, and large, attractive fruits. Place in a higher light location for the best flower and fruit display. Best used for naturalizing, mass plantings, and wetland reclamation projects. The berries are edible, but only palatable when […]
Useful as a bank cover or large scale groundcover. Transplants well. This plant has a beautiful fruit show and is shade tolerant, however, it is also a twiggy, “garbage can plant” (collects leaves and blowing debris); this quality (especially prominent in the fall and winter) limits its usability in the landscape. […]
In the wild, this species can reach over a staggering 200′. Many uses for this tree are for spacious parks and screening. […]
