Clerodendrum trichotomum (harlequin glorybower, glorytree, peanut butter tree) is a species of flowering plant in the genus Clerodendrum. It is placed in the family Lamiaceae, or sometimes the Verbenaceae. It is native to China, Korea, Taiwan, Japan, and India.[1]
It is a large shrub, growing 3–6 metres (10–20 ft) high. The leaves are ovate, up to 12 cm (5 in) long, soft and downy or hairy, producing a peanut odor when crushed. The fragrant flowers are borne on branching peduncles. They have white petals, held within a green calyx which turns red as the fruits ripen. The fruits (drupes) are white, changing to bright blue and eventually dark blue on maturity.[2] They contain the novel blue pigment Trichotomine.[3]
It is cultivated for its fragrant flowers, autumn colour, and ornamental berries. It is hardy but requires a sheltered position. The variety C. trichotomum var. fargesii (Farges' harlequin glorybower) has gained the Royal Horticultural Society's Award of Garden Merit.[4]
