Striped leaf allantoma Plant Care

Striped leaf allantoma (Allantoma lineata) belongs to the Lecythidaceae family within the Allantoma genus. Striped leaf allantoma is native to Amazonas State in Venezuela, and also to Amazonas and Pará States in Brazil. Striped leaf allantoma is also known as Lineated allantoma.

Striped leaf allantoma displays a tall tree, spreading canopy growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Striped leaf allantoma produces large showy white flowers with prominent stamens.

Leaf size: approximately 12 inches.

Water a young or newly planted Striped leaf allantoma 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.

Striped leaf allantoma thrives in partial shade to full sun.

Allantoma lineata tolerates temperatures of 65–85°F. Striped leaf allantoma prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with high organic content. Good drainage is essential for Striped leaf allantoma to prevent waterlogging, which leads to root rot and fungal issues.

Feed Striped leaf allantoma 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 partial shade to full sun and rich, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Striped leaf allantoma is suited to USDA Zone 11b – 12b.

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.

Striped leaf allantoma can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Striped leaf allantoma 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.

Striped leaf allantoma is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Striped leaf allantoma can be propagated through seeds, air layering. Similar propagation techniques also apply to allantoma integrifolia plant care, which shares the same genus.

Striped leaf allantoma is susceptible to aphids, scale insects, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Striped leaf allantoma grows outdoors in USDA Zone 11b – 12b. It survives winters down to planting zone 11b. Striped leaf allantoma is native to Amazonas State in Venezuela, and also to Amazonas and Pará States in Brazil. In cooler regions, grow Striped leaf allantoma as a houseplant or bring it indoors before the first frost.
