Sticky Star-flower Plant Care

Sticky Star-flower (Calytrix glutinosa) belongs to the Myrtaceae family within the Calytrix genus. Sticky Star-flower is native to the south-west of Western Australia.

Sticky Star-flower displays a compact, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 3 ft. Sticky Star-flower produces small, star-shaped flowers in shades of pink, white, or purple.

Leaf size: approximately 2 inches.

Water a young or newly planted Sticky Star-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.

Sticky Star-flower thrives in full sun to partial shade.

Calytrix glutinosa tolerates temperatures of 50–80°F. Sticky Star-flower prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter like compost. Good drainage is essential for Sticky Star-flower to prevent waterlogging, which leads to root rot and fungal issues.

Feed Sticky Star-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.

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

Sticky Star-flower is suited to USDA Zone 12a.

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.

Sticky Star-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 Sticky Star-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.

Sticky Star-flower is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Sticky Star-flower can be propagated through seeds, semi-hardwood cuttings. Similar propagation techniques also apply to bristleless starflower plant care, which shares the same genus.

Sticky Star-flower 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.

Sticky Star-flower grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Sticky Star-flower is native to the south-west of Western Australia. In cooler regions, grow Sticky Star-flower as a houseplant or bring it indoors before the first frost.
