More often planted than our native California western redbud and more showy. It volunteers freely on campus, for example on Stanford Avenue. The seed pods are narrower than those of California redbud and fall off earlier. The heart-shaped 5-inch leaf blade is broader than it is long, darker green above than below, and has a sharp tip. Western redbud has a similar leaf but rounded at the tip or slightly notched. Strikingly, flowers are produced along the branches and trunk before leaves appear. The related C. siliquastrum is called the Judas tree since Judas Iscariot reportedly hanged himself from one (see Name derivation below).

See eastern redbuds on Santa Teresa Street at the New Guinea Garden, and between the McCullough and Gordon and Betty Moore buildings with western redbud. The two species are paired in the roundabout on Escondido Road and Campus Drive as well: three single-trunked westerns with one multitrunk eastern. In Palo Alto, a specimen at 1031 Hamilton Avenue is actually around the corner on Chaucer Street.

Cultivar ‘Forest Pansy’ has distinctive reddish purple leaves, but puts on more of a muted show when in flower. Several are in the Knight Management Center (which opened spring 2011) on Serra Street, in the walkway between the MBA Class of 1998 building and the Patterson building. They were part of the original landscaping of the Serra Street Complex at that location.

Name derivation: Cercis – Greek name kerkis, probably for a poplar, but also applied to C. siliquastrum, which through confusion between Judas and Judaea, is now traditionally the trees from which Jesus was hanged; canadensis – of Canada. – William T. Stearn, Stearn’s Dictionary of Plant Names for Gardeners, Portland, OR.: Timber Press, 1996.
