Cultivars/Varieties

While many cultivars exist, the only types available commercially are weeping cultivars.

'Pendula' - This cultivar is an umbrella for various pendulous forms which are usually grafted on a standard to form a small weeping tree.

'Varied Directions' - A unique plant developed by Dr. Sid Waxman of the University of Connecticut, this cultivar forms a weeping, spreading plant with main branches that radiate out in an irregular pattern (hence the name). The ultimate form of this plant seems to depend on the graft height, as it may form a prostrate shrub or small tree.
