Brunia thomae Plant Care

Brunia thomae (Brunia thomae) belongs to the Bruniaceae family within the Brunia genus. Brunia thomae is native to the Western Cape.

Brunia thomae displays a compact, rounded shrub growth habit, reaching up to 2 ft tall with a spread of approximately 2 ft. Brunia thomae produces small, clustered flowers in white or pink.

Leaf size: approximately 1.5 inches.

Water a young or newly planted Brunia thomae 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.

Brunia thomae thrives in bright indirect light. Avoid placing Brunia thomae in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Brunia thomae tolerates temperatures of 60–75°F. Brunia thomae prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining acidic soil mix with peat moss and perlite. Good drainage is essential for Brunia thomae to prevent waterlogging, which leads to root rot and fungal issues.

Feed Brunia thomae 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.

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

Choose a spot with bright indirect light and well-draining acidic soil mix with peat moss and perlite. Avoid low spots where water collects after rain.

Brunia thomae is suited to USDA Zone 13a.

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.

Brunia thomae can spread to about 2 ft (0.6 m) and reach about 2 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 Brunia thomae 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.

Brunia thomae is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Brunia thomae can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to cape heath plant care, which shares the same genus.

Brunia thomae is susceptible to aphids, spider mites, scale insects. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Brunia thomae grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Brunia thomae is native to the Western Cape. In cooler regions, grow Brunia thomae as a houseplant or bring it indoors before the first frost.
