Lanceleaf Acmella Plant Care

Lanceleaf Acmella (Acmella lanceolata) belongs to the Asteraceae family within the Acmella genus. Lanceleaf Acmella is native to Brazil, Peru. Lanceleaf Acmella is also known as Acmella lanceolata, Amellus carolinianus, Anthemis cotula.

Lanceleaf Acmella displays a low rosette, spreading growth habit, reaching up to 1 ft tall with a spread of approximately 1 ft. Lanceleaf Acmella produces small yellow or red button-like flowers.

Leaf size: approximately 1 inches.

Water a young or newly planted Lanceleaf Acmella 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.

Lanceleaf Acmella thrives in full sun to partial shade.

Acmella lanceolata tolerates temperatures of 65–85°F. Lanceleaf Acmella prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

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

Feed Lanceleaf Acmella every 2 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

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.

Lanceleaf Acmella is suited to USDA Zone 10a – 11b.

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.

Lanceleaf Acmella 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 Lanceleaf Acmella 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.

Lanceleaf Acmella is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Lanceleaf Acmella can be propagated through seeds, division of clumps. Similar propagation techniques also apply to white acmella plant care, which shares the same genus.

Lanceleaf Acmella 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.

Lanceleaf Acmella grows outdoors in USDA Zone 10a – 11b. It survives winters down to planting zone 10a. Lanceleaf Acmella is native to Brazil, Peru. In cooler regions, grow Lanceleaf Acmella as a houseplant or bring it indoors before the first frost.
