Small-flower Smokebush Plant Care

Small-flower Smokebush (Conospermum microflorum) belongs to the Proteaceae family within the Conospermum genus. Small-flower Smokebush is native to Western Australia.

Small-flower Smokebush displays an upright, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Small-flower Smokebush produces small, tubular flowers in shades of white, pink, or purple.

Leaf size: approximately 4 inches.

Water a young or newly planted Small-flower Smokebush 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.

Small-flower Smokebush thrives in full sun to partial shade.

Conospermum microflorum tolerates temperatures of 50–80°F. Small-flower Smokebush prefers humidity levels of 40–60%.

Well-draining sandy soil with added organic matter for nutrients. Good drainage is essential for Small-flower Smokebush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Small-flower Smokebush 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 with added organic matter for nutrients. Avoid low spots where water collects after rain.

Small-flower Smokebush 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.

Small-flower Smokebush 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 Small-flower Smokebush 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.

Small-flower Smokebush 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.

Small-flower Smokebush can be propagated through seeds, cuttings. Similar propagation techniques also apply to smokebush plant care, which shares the same genus.

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