Encelia asperifolia Plant Care

Encelia asperifolia (Encelia asperifolia) belongs to the Asteraceae family within the Encelia genus. Encelia asperifolia is native to northwestern Mexico.

Encelia asperifolia displays a low, spreading shrub growth habit, reaching up to 1.5 ft tall with a spread of approximately 2 ft. Encelia asperifolia produces bright yellow daisy-like flowers.

Leaf size: approximately 3 inches.

Water a young or newly planted Encelia asperifolia every 7–14 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.

Encelia asperifolia thrives in full sun.

Encelia asperifolia tolerates temperatures of 50–90°F. Encelia asperifolia prefers humidity levels of 30–60%.

Well-draining sandy soil mix with some organic matter. Good drainage is essential for Encelia asperifolia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Encelia asperifolia 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 and well-draining sandy soil mix with some organic matter. Avoid low spots where water collects after rain.

Encelia asperifolia 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.

Encelia asperifolia can spread to about 2 ft (0.6 m) and reach about 2 ft (0 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 Encelia asperifolia 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.

Encelia asperifolia 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.

Encelia asperifolia can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to california brittlebush plant care, which shares the same genus.
