Abstract:
PLANTS:

Cercis chinensis ‘Don Egolf’. A fruitless selection of Cercis chinensis, ‘Don Egolf’ is the first redbud cultivar to be introduced by the U.S. National Arboretum. This cultivar was selected from a population of open-pollinated seed obtained from a botanical garden in Kunming, the People's Republic of China. ‘Don Egolf’ was selected for its compact, slow-growing, vase-shaped habit; dark green, pest-resistant foliage; abundant rosy mauve flowers; absence of seed pods; and high field tolerance to Botryosphaeria dothidia canker. It is readily propagated from semihardwood cuttings using 3000 ppm IBA in talc. Hardy in U.S.D.A. Zones 6 to 9, in 15 years it has grown 9 ft tall and 9½ ft wide. Evaluated by cooperators in 14 states throughout the U.S. It has shown no signs of invasiveness.
