Restio subverticillatus Plant Care

Restio subverticillatus (Restio subverticillatus) belongs to the Restionaceae family within the Restio genus. Restio subverticillatus is native to the southwestern Cape Provinces of South Africa.

Restio subverticillatus displays a clumping, upright growth habit, reaching up to 4 ft tall with a spread of approximately 2 ft. Restio subverticillatus produces small inconspicuous flowers.

Leaf size: approximately 12 inches.

Water a young or newly planted Restio subverticillatus 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.

Restio subverticillatus thrives in full sun to partial shade.

Restio subverticillatus tolerates temperatures of 50–80°F. Restio subverticillatus prefers humidity levels of 40–70%.

Well-draining sandy soil with high organic content. Good drainage is essential for Restio subverticillatus to prevent waterlogging, which leads to root rot and fungal issues.

Feed Restio subverticillatus 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 high organic content. Avoid low spots where water collects after rain.

Restio subverticillatus 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.

Restio subverticillatus can spread to about 2 ft (0.6 m) and reach about 4 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 Restio subverticillatus 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.

Restio subverticillatus 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.

Restio subverticillatus can be propagated through division, seeds.

Restio subverticillatus grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Restio subverticillatus is native to the southwestern Cape Provinces of South Africa. In cooler regions, grow Restio subverticillatus as a houseplant or bring it indoors before the first frost.
