Additional Information

A highly ornamental native tree, even though the pendulous clusters of flowers do not appear in great numbers every year. Well-adapted to Midwest conditions. Develops a tap root. Does not flower fully each year; part of a tree may flower one year, part the next, but the effect is striking even when only certain branches bear flowers. Bees are attracted to the flowers. Flowers appear only after many years from seed. Avoid pruning in spring or there will be much bleeding (sap flow) over the bark.
