White Xanthosia Plant Care

White Xanthosia (Xanthosia candida) belongs to the Apiaceae family within the Xanthosia genus. White Xanthosia is native to the south-west of Western Australia.

White Xanthosia displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. White Xanthosia produces small clusters of tiny white or pink flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted White Xanthosia every 3–5 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 Xanthosia thrives in partial shade to full shade. The optimal light range is 50–200 lux. Avoid placing White Xanthosia in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Xanthosia candida tolerates temperatures of 60–75°F. White Xanthosia prefers humidity levels of 40–60%.

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

Feed White Xanthosia 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 partial shade to full shade and well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

White Xanthosia 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.

White Xanthosia can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune White Xanthosia 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 Xanthosia 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.

White Xanthosia can be propagated through seeds, division of root clumps. Similar propagation techniques also apply to xanthosia atkinsoniana plant care, which shares the same genus.

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

White Xanthosia grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. White Xanthosia is native to the south-west of Western Australia. In cooler regions, grow White Xanthosia as a houseplant or bring it indoors before the first frost.
