Genus: Cercis (SEER-sis)
Origin: Native to East Asia, Southern Europe, United States and Mexico
Characteristics: Members of the pea family, the genus consists of 7 species of shrubs and small trees. Small pea-flowers are white, pink or magenta; occur in clusters or short chains (racemes), usually on old wood in early spring. Leaves are heart-shape and can be green, gold, purple or variegated. Leathery seed pods resemble pea pods and occur in summer.
Size: Shrub forms are multi-stemmed and grow 8-10’ x 8-10’. Tree forms range between 10’ at maturity to 25-30’. Weeping forms grow to 8’ x 8’.
Culture: Sun or part shade, adapts to many soil types, but cannot survive in a site that is permanently wet. Cercis grows better when planted in a spot that is not in a sprinkler zone during summer. In heavy clay soils, amend with compost & pumice to increase soil drainage. Provide deep watering, every 2 weeks in the first summer (if it gets really hot, say over 95 degrees, give an additional soaking before the heat comes). Cercis is drought tolerant once established.
Problems: Susceptible to Verticillium wilt — read more about it here.
With insufficient soil drainage, trees can experience root rot. This is likely the leading cause of death of Cercis in Portland.
