Three-stamen Omphalea Plant Care

Three-stamen Omphalea (Omphalea triandra) belongs to the Euphorbiaceae family within the Omphalea genus. Three-stamen Omphalea is native to Jamaica and Haiti. Three-stamen Omphalea is also known as Mountain Pride.

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

Leaf size: approximately 5 inches.

Water a young or newly planted Three-stamen Omphalea 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.

Three-stamen Omphalea thrives in partial to full sun.

Omphalea triandra tolerates temperatures of 60–85°F. Three-stamen Omphalea 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 Three-stamen Omphalea to prevent waterlogging, which leads to root rot and fungal issues.

Feed Three-stamen Omphalea 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.

Three-stamen Omphalea is suited to USDA Zone 10b – 12b.

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.

Three-stamen Omphalea 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 Three-stamen Omphalea 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.

Three-stamen Omphalea 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.

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

Three-stamen Omphalea 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.

Three-stamen Omphalea grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Three-stamen Omphalea is native to Jamaica and Haiti. In cooler regions, grow Three-stamen Omphalea as a houseplant or bring it indoors before the first frost.
