Asterolasia hexapetala Plant Care

Asterolasia hexapetala (Asterolasia hexapetala) belongs to the Rutaceae family within the Asterolasia genus. Asterolasia hexapetala is native to the Warrumbungles in New South Wales.

Asterolasia hexapetala displays a compact, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Asterolasia hexapetala produces small white flowers in clusters.

Leaf size: approximately 3 inches.

Water a young or newly planted Asterolasia hexapetala 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.

Asterolasia hexapetala thrives in full sun to partial shade.

Asterolasia hexapetala tolerates temperatures of 60–80°F. Asterolasia hexapetala prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Asterolasia hexapetala to prevent waterlogging, which leads to root rot and fungal issues.

Feed Asterolasia hexapetala 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.

Choose a spot with full sun to partial shade and well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Asterolasia hexapetala 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.

Asterolasia hexapetala can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Asterolasia hexapetala 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.

Asterolasia hexapetala 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.

Asterolasia hexapetala can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to starflower plant care, which shares the same genus.

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

Asterolasia hexapetala grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Asterolasia hexapetala is native to the Warrumbungles in New South Wales. In cooler regions, grow Asterolasia hexapetala as a houseplant or bring it indoors before the first frost.
