American Yellowwood can create one of the most spectacular flower display of any tree species. The blossoms appear in late spring, when numerous fragrant wisteria-like foot-long flower clusters droop from the branches. The mature American Yellowwood tree in full bloom is a stunning sight.
In recognition of its beauty, the species was given the prestigious Pennsylvania Horticultural Society Gold Award in 1994. It is a graceful medium-sized, deciduous tree that typically grows 30-40 feet tall with upright branching and a broad, rounded crown covered with intensely fragrant, wisteria-like flowers in large, drooping, terminal panicles (10-15 inches long) in late spring. Younger specimens grow well in some shade and away from high wind areas. USDA zones 4-8
