Smallflower Copperburr Plant Care

Smallflower Copperburr (Sclerolaena parviflora) belongs to the Amaranthaceae family within the Sclerolaena genus. Smallflower Copperburr is native to every mainland state and territory of Australia.

Smallflower Copperburr displays a low spreading shrub growth habit, reaching up to 1.5 ft tall with a spread of approximately 2 ft. Smallflower Copperburr produces small inconspicuous flowers.

Leaf size: approximately 2.5 inches.

Water a young or newly planted Smallflower Copperburr every 10–14 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.

Smallflower Copperburr thrives in full sun to partial shade.

Sclerolaena parviflora tolerates temperatures of 60–85°F. Smallflower Copperburr prefers humidity levels of 30–60%.

Well-draining sandy soil mix with added organic matter. Good drainage is essential for Smallflower Copperburr to prevent waterlogging, which leads to root rot and fungal issues.

Feed Smallflower Copperburr 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 soil mix with added organic matter. Avoid low spots where water collects after rain.

Smallflower Copperburr 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.

Smallflower Copperburr can spread to about 2 ft (0.6 m) and reach about 2 ft (0 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 Smallflower Copperburr 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.

Smallflower Copperburr 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.

Smallflower Copperburr can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to spiny poverty bush plant care, which shares the same genus.
