A native of China, Korea, Japan, Taiwan, and parts of South Asia, Clerodendrum trichotomum has been cultivated in Western gardens since the mid-1800s, when the shrub was introduced from Japan and quickly adopted across Europe and the American South for uncanny late-season performance. This is the hardiest member of the genus and, for our money, the most theatrical.

Through August and September, broad cymes of white tubular flowers open from swollen pink calyces at the branch tips, carrying a sweet jasmine-like fragrance that drifts farther than you would expect from a shrub this size. Hummingbirds, swallowtails, and night-flying moths work the flowers steadily. What follows is the part collectors plant the shrub for: the petals drop, the pink calyces flush deeper to a true rose-red and open like little stars, and at the center of each one sits a single hard berry the color of oxidized turquoise. The contrast is almost gaudy, pink, red, metallic blue, and it holds for weeks into autumn.

Harlequin glorybower reaches 10 to 15 feet as a multi-stemmed shrub, more if trained as a small tree. The roots sucker freely, which is either a feature or a problem depending on the site: in an open lawn or border the plant will form a colony; in a contained bed or beside a drive, an occasional pruning keeps it well-mannered. Sun to part shade, average to moist soil, hardy in zones 7 to 9. Crush a leaf and you will understand why some call this the peanut butter tree.

Design Notes

A theatrical, late-season shrub for a sunny to part-shaded border, a woodland edge, or a large mixed planting, grown for fragrant August flowers and the astonishing pink, red, and turquoise fruit display that follows into autumn. The roots sucker freely, so site where a colony is welcome, in an open lawn or naturalistic bed, or contain the edges beside a drive with occasional pruning. Give average to moist, well-drained soil, and place near a path or seating where the jasmine-scented bloom and the odd peanut-scented foliage can be met up close. Can be trained up as a small multi-stemmed tree.

Flower, Fruit & Foliage

Showy 1 to 1.5 inch white flowers on 6 to 9 inch cymes, fragrant, summer -fall

Flower: Fragrant white tubular flowers in loose terminal cymes, August through September, emerging from inflated pink calyces. Strongly scented, attractive to hummingbirds, butterflies, and moths.

Foliage: Opposite, ovate, soft dark green leaves to 5 inches long. Releases a distinct peanut-like scent when bruised.

Fruit: Glossy turquoise-blue drupes set against persistent five-pointed rose-red calyces, ripening September through October. One of the most striking fruit displays of any hardy shrub.

Care

Read our full care guide

Light. Full sun to part shade; more sun gives heavier flower and fruit, with light shade welcome in the hottest gardens.

Soil. Average to moist, well-drained ground enriched with compost; adaptable, but not for constantly wet or bone-dry sites.

Water. Water regularly through establishment and in summer drought; once settled the shrub is fairly self-reliant.

Pruning. Prune in late winter to shape and to lift into a small tree if wished; remove root suckers to keep the colony in bounds, or leave them to spread where a thicket is welcome.

Hardiness. USDA zones 7 to 9; the hardiest of the glorybowers, resprouting from the root after a hard freeze.

History & tradition

In China, Korea, and Japan the harlequin glorybower is also a traditional medicine, known in Chinese as chou wu tong. The leaves, gathered traditionally before flowering, have long been decocted to bring down high blood pressure and to ease the joint pain, swelling, and numbness of what practitioners describe as wind-damp conditions, while leaf preparations were applied externally for itching skin and dermatitis. Modern work has taken an interest: a mid-twentieth-century clinical trial reported meaningful drops in blood pressure, and reviews describe anti-inflammatory, antioxidant, and mild sedative activity, though rigorous clinical evidence remains limited.
