Mexican Hand Flower Plant Care

Mexican Hand Flower (Chiranthodendron pentadactylon) belongs to the Malvaceae family within the Chiranthodendron genus. Mexican Hand Flower is also known as Devil's Hand Tree, Flame Tree.

Mexican Hand Flower displays a small to medium-sized tree growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Mexican Hand Flower produces showy red or pink flowers with prominent stamens.

Leaf size: approximately 6 inches.

Water a young or newly planted Mexican Hand Flower 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.

Mexican Hand Flower thrives in full sun to partial shade.

Chiranthodendron pentadactylon tolerates temperatures of 60–80°F. Mexican Hand Flower prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with added organic matter like compost or peat moss. Good drainage is essential for Mexican Hand Flower to prevent waterlogging, which leads to root rot and fungal issues.

Feed Mexican Hand Flower 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 rich, well-draining soil with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Mexican Hand Flower is suited to USDA Zone 13a.

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.

Mexican Hand Flower can spread to about 15 ft (4.6 m) and reach about 20 ft (6 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Mexican Hand Flower 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.

Mexican Hand Flower is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Mexican Hand Flower can be propagated through seeds, stem cuttings.
