Plant Profile: Harlequin Glorybower (Clerodendrum trichotomum)

clerodendrum-trichotomum Harlequin GlorybowerThis large coarse shrub, native to China and Japan, is deciduous or semi-evergreen, and is cultivated for its scented flowers and unusual berries.  It is a member of the deadnettle family, Lamiaceae, that also includes adjuga, beebalm, and mint. Growing to fifteen feet and as wide, it can be trained as a small tree but is more often seen as a suckering shrub. In mid- to late-summer, the plant produces clusters of very fragrant white flowers that are followed by brilliant blue berries surrounded by a fleshy red calyx. The dark green leaves are downy and produce an odor resembling peanut butter or green peas when crushed. Use in shrub border. Plants grown in the northern range of their zone may die back in winter but will return in spring.  The genus name, Clerodendrum, comes from the Greek words kleros meaning chance and dendron meaning tree and may refer to the variable medicinal qualities of the plants.  The specific epithet, trichotomum, may be  derived from Greek, and  mean three-forked or triple-branched.
