Kalopanax pictus

An excellent large tropical looking shade tree, hardy to zone four and reaching up to 90’ in height, Flowers are typical of many members of the Araliaceae, white in small clusters grouped to form 2’ terminal panicles which are displayed well above the foliage, and are loved by bees; fruits are a small black drupe which the birds quickly devour. The leaves are huge and Castor Bean-like hence the common name Castor Aralia, the genus is monotypic which automatically raises it several notches on the desirability scale, Does anyone know of a variegated form?
