Chromolaena sinuata Plant Care

Chromolaena sinuata (Chromolaena sinuata) belongs to the Asteraceae family within the Chromolaena genus.

Chromolaena sinuata displays an upright, spreading shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Chromolaena sinuata produces small white or lavender flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Chromolaena sinuata 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.

Chromolaena sinuata thrives in full sun to partial shade.

Chromolaena sinuata tolerates temperatures of 65–85°F. Chromolaena sinuata prefers humidity levels of 40–70%.

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

Feed Chromolaena sinuata every 4 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. Avoid low spots where water collects after rain.

Chromolaena sinuata is suited to USDA Zone 13b.

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.

Chromolaena sinuata 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 Chromolaena sinuata 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.

Chromolaena sinuata 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.

Chromolaena sinuata can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to bigelow's thoroughwort plant care, which shares the same genus.

Chromolaena sinuata 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.

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