Phellodendron (Rutaceae) BSWJ11175

japonicum

A small tree to only 5m tall that we collected seed of in the high mountains of eastern Shikoku Japan in 2005 at 1150m. With a bare trunk merging into wide-spreading branches, bearing 9-15 leafleted pinnate downy leaves, that transform to a bright yellow in the autumn. Which is when the plump black fruit held in terminal cymes are borne resulting from the yellowish flowers June-July. Easily grown in any type (even chalk) of fertile drained soil in sun or part shade.
