White Serruria Plant Care

White Serruria (Serruria candicans) belongs to the Proteaceae family within the Serruria genus. White Serruria is native to the Western Cape.

White Serruria displays an upright, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. White Serruria produces showy, colorful flowers in shades of pink, red, or white.

Leaf size: approximately 4 inches.

Water a young or newly planted White Serruria 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.

White Serruria thrives in full sun to partial shade.

Serruria candicans tolerates temperatures of 50–80°F. White Serruria prefers humidity levels of 40–60%.

Well-draining acidic soil mix with added sand and peat moss. Good drainage is essential for White Serruria to prevent waterlogging, which leads to root rot and fungal issues.

Feed White Serruria 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 acidic soil mix with added sand and peat moss. Avoid low spots where water collects after rain.

White Serruria 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.

White Serruria 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 White Serruria 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.

White Serruria 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.

White Serruria can be propagated through seeds, cuttings. Similar propagation techniques also apply to serruria acrocarpa plant care, which shares the same genus.

White Serruria 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.

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