Castrilanthemum debeauxii Plant Care

Castrilanthemum debeauxii (Castrilanthemum debeauxii) belongs to the Asteraceae family within the Castrilanthemum genus.

Castrilanthemum debeauxii displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Castrilanthemum debeauxii produces daisy-like flowers in various colors such as yellow, white, and purple.

Leaf size: approximately 3 inches.

Water a young or newly planted Castrilanthemum debeauxii 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.

Castrilanthemum debeauxii thrives in full sun to partial shade.

Castrilanthemum debeauxii tolerates temperatures of 60–80°F. Castrilanthemum debeauxii prefers humidity levels of 40–70%.

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

Feed Castrilanthemum debeauxii 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 for moisture retention. Avoid low spots where water collects after rain.

Castrilanthemum debeauxii 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.

Castrilanthemum debeauxii 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 Castrilanthemum debeauxii 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.

Castrilanthemum debeauxii 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.

Castrilanthemum debeauxii can be propagated through seeds, division of clumps.

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

Castrilanthemum debeauxii grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Castrilanthemum debeauxii as a houseplant or bring it indoors before the first frost.
