Cultivars of Three North American Trees
Registered landscape architects and ISA certified arborists
This course is part of an on-going series about cultivars of various trees. In this course, we discuss the cultivars of three popular native American trees. The cultivars have been selected for various purposes including pest and disease resistance, urban environment sustainability, survival around utilities and general superiority to the straight species when used in the urban environment.
