Jamaican Rain Tree Plant Care

Jamaican Rain Tree (Brya ebenus) belongs to the Fabaceae family within the Brya genus. Jamaican Rain Tree is native to Cuba, and it has been introduced to Jamaica. Jamaican Rain Tree is also known as Green Ebony, Cocus Wood, Amerimnon ebenus.

Jamaican Rain Tree displays a tall, upright shrub growth habit, reaching up to 5 ft tall with a spread of approximately 3 ft. Jamaican Rain Tree produces small clusters of white or pink flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Jamaican Rain Tree every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Jamaican Rain Tree thrives in full sun to partial shade.

Brya ebenus tolerates temperatures of 60–80°F. Jamaican Rain Tree prefers humidity levels of 40–70%.

Well-draining loamy soil with added organic matter for nutrients. Good drainage is essential for Jamaican Rain Tree to prevent waterlogging, which leads to root rot and fungal issues.

Feed Jamaican Rain Tree every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with full sun to partial shade and well-draining loamy soil with added organic matter for nutrients. Avoid low spots where water collects after rain.

Jamaican Rain Tree is suited to USDA Zone 10a – 11b.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Jamaican Rain Tree can spread to about 3 ft (0.9 m) and reach about 5 ft (2 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Jamaican Rain Tree while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

Jamaican Rain Tree is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Jamaican Rain Tree can be propagated through seeds, stem cuttings.
