Phaleria octandra Plant Care

Phaleria octandra (Phaleria octandra) belongs to the Thymelaeaceae family within the Phaleria genus. Phaleria octandra is native to Malesia, New Guinea, the Solomon Islands, and the Northern Territory and Queensland in Australia.

Phaleria octandra displays an upright, dense shrub growth habit, reaching up to 4 ft tall with a spread of approximately 3 ft. Phaleria octandra produces small, fragrant flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Phaleria octandra every 7–10 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.

Phaleria octandra thrives in bright indirect light. Avoid placing Phaleria octandra in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Phaleria octandra tolerates temperatures of 65–80°F. Phaleria octandra prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, slightly acidic soil with added organic matter like peat moss. Good drainage is essential for Phaleria octandra to prevent waterlogging, which leads to root rot and fungal issues.

Feed Phaleria octandra 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 bright indirect light and well-draining, slightly acidic soil with added organic matter like peat moss. Avoid low spots where water collects after rain.

Phaleria octandra is suited to USDA Zone 13b.

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.

Phaleria octandra 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 Phaleria octandra 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.

Phaleria octandra 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.

Phaleria octandra can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to phaleria capitata plant care, which shares the same genus.

Phaleria octandra 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.

Phaleria octandra grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Phaleria octandra is native to Malesia, New Guinea, the Solomon Islands, and the Northern Territory and Queensland in Australia. In cooler regions, grow Phaleria octandra as a houseplant or bring it indoors before the first frost.
