Actinella linearis Plant Care

Actinella linearis (Actinella linearis) belongs to the Asteraceae family within the Actinella genus. Actinella linearis is native to the southwestern and south-central United States and northern Mexico.

Actinella linearis displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Actinella linearis produces small daisy-like flowers in shades of yellow, orange, or red.

Leaf size: approximately 2 inches.

Water a young or newly planted Actinella linearis 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.

Actinella linearis thrives in full sun to partial shade.

Actinella linearis tolerates temperatures of 50–75°F. Actinella linearis prefers humidity levels of 40–70%.

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

Feed Actinella linearis 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.

Actinella linearis 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.

Actinella linearis can spread to about 2 ft (0.5 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Actinella linearis 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.

Actinella linearis 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.

Actinella linearis can be propagated through seeds, division of clumps.

Actinella linearis 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.

Actinella linearis grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Actinella linearis is native to the southwestern and south-central United States and northern Mexico. In cooler regions, grow Actinella linearis as a houseplant or bring it indoors before the first frost.
