Omphalea ankaranensis Plant Care

Omphalea ankaranensis (Omphalea ankaranensis) belongs to the Euphorbiaceae family within the Omphalea genus. Omphalea ankaranensis is native to a small region in northern Madagascar.

Omphalea ankaranensis displays a bushy shrub growth habit, reaching up to 4 ft tall with a spread of approximately 3 ft. Omphalea ankaranensis produces small greenish flowers in clusters.

Leaf size: approximately 5 inches.

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

Omphalea ankaranensis thrives in partial to full sun.

Omphalea ankaranensis tolerates temperatures of 60–85°F. Omphalea ankaranensis prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining sandy soil mix with organic matter. Good drainage is essential for Omphalea ankaranensis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Omphalea ankaranensis every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with partial to full sun and well-draining sandy soil mix with organic matter. Avoid low spots where water collects after rain.

Omphalea ankaranensis is suited to USDA Zone 13a.

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

Omphalea ankaranensis can spread to about 3 ft (0.9 m) and reach about 4 ft (1 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 Omphalea ankaranensis 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 shrub in one year.

Omphalea ankaranensis 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.

Omphalea ankaranensis can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to omphalea celata plant care, which shares the same genus.

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

Omphalea ankaranensis grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Omphalea ankaranensis is native to a small region in northern Madagascar. In cooler regions, grow Omphalea ankaranensis as a houseplant or bring it indoors before the first frost.
