Clerodendrum trichotomum, the harlequin glorybower, glorytree or peanut butter tree, is a species of flowering plant in the family Lamiaceae. It is native to China, Korea, Taiwan, Japan, India, and the Philippines.[2][3]
It is a large deciduous 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.[4] They contain the novel blue pigment trichotomine.[5]
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) and the cultivar C. trichotomum var. fargesii 'Carnival'[6] have gained the Royal Horticultural Society's Award of Garden Merit.[7] (confirmed 2017).[8]
Etymology
Clerodendrum is derived from Greek, and means 'chance tree'.[9]
Trichotomum is also derived from Greek, and means 'three-forked' or 'triple-branched'.[9]
