Showy Rabbitbrush Plant Care

Showy Rabbitbrush (Chrysothamnus stylosus) belongs to the Asteraceae family within the Chrysothamnus genus. Showy Rabbitbrush is native to Arizona and Utah in the southwestern United States. Showy Rabbitbrush is also known as Grindelia stylosa, Vanclevea stylosa.

Showy Rabbitbrush displays an upright, branching shrub growth habit, reaching up to 4 ft tall with a spread of approximately 3 ft. Showy Rabbitbrush produces small yellow flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Showy Rabbitbrush 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.

Showy Rabbitbrush thrives in full sun to partial shade.

Chrysothamnus stylosus tolerates temperatures of 50–85°F. Showy Rabbitbrush prefers humidity levels of 30–60%.

Well-draining sandy soil with added organic matter for nutrients. Good drainage is essential for Showy Rabbitbrush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Showy Rabbitbrush 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 soil with added organic matter for nutrients. Avoid low spots where water collects after rain.

Showy Rabbitbrush 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.

Showy Rabbitbrush can spread to about 3 ft (0.9 m) and reach about 4 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Showy Rabbitbrush 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.

Showy Rabbitbrush 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.

Showy Rabbitbrush can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to low rabbitbrush plant care, which shares the same genus.
