At the Station, we have noted this accessions' striking yellow fall color. Ames 21900 is another seedling population collected in 1994 by Michael Knudson from the Mckenzie Game Management Area near Bismarck, North Dakota, and it would be of interest to compare its habit and hardiness to A21775. Probable hardiness USDA Zone 3. This is a tree of striking tropical appearance growing to 60 feet under cultivation. They are similar in shape to the leaves of Sweetgum.
Petioles are often longer than the blades.
Fall color is not notable. The panicles are borne in great numbers. Small drupes ripen to black in September-October and are reported to be consumed by birds. This species is long lived, trouble free and tolerant of alkaline soils. Mature specimens are said to be quite impressive.
