Showy Riceflower Plant Care

Showy Riceflower (Pimelea spectabilis) belongs to the Thymelaeaceae family within the Pimelea genus. Showy Riceflower is native to the south-west of Western Australia. Showy Riceflower is also known as Spectacular Riceflower.

Showy Riceflower displays a compact, bushy shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 3 ft. Showy Riceflower produces small clusters of pink, white, or yellow flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Showy Riceflower 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.

Showy Riceflower thrives in full sun to partial shade.

Pimelea spectabilis tolerates temperatures of 60–75°F. Showy Riceflower prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining acidic soil mix with added organic matter like peat moss or pine bark. Good drainage is essential for Showy Riceflower to prevent waterlogging, which leads to root rot and fungal issues.

Feed Showy Riceflower 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 full sun to partial shade and well-draining acidic soil mix with added organic matter like peat moss or pine bark. Avoid low spots where water collects after rain.

Showy Riceflower 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.

Showy Riceflower can spread to about 3 ft (0.9 m) and reach about 3 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 Showy Riceflower 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.

Showy Riceflower 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.

Showy Riceflower can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to coastal rice flower plant care, which shares the same genus.

Showy Riceflower 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.
