Stiff rice-flower Plant Care

Stiff rice-flower (Pimelea stricta) belongs to the Thymelaeaceae family within the Pimelea genus. Stiff rice-flower is native to south-eastern continental Australia.

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

Leaf size: approximately 2 inches.

Water a young or newly planted Stiff rice-flower 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.

Stiff rice-flower thrives in full sun to partial shade.

Pimelea stricta tolerates temperatures of 60–75°F. Stiff rice-flower 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 Stiff rice-flower to prevent waterlogging, which leads to root rot and fungal issues.

Feed Stiff rice-flower 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.

Stiff rice-flower 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.

Stiff rice-flower 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 Stiff rice-flower 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.

Stiff rice-flower 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.

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

Stiff rice-flower 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.

Stiff rice-flower grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Stiff rice-flower is native to south-eastern continental Australia. In cooler regions, grow Stiff rice-flower as a houseplant or bring it indoors before the first frost.
