Bolus' Sceptrum Plant Care

Bolus' Sceptrum (Paranomus bolusii) belongs to the Proteaceae family within the Paranomus genus. Bolus' Sceptrum is native to the Western Cape, South Africa.

Bolus' Sceptrum displays a low, spreading shrub growth habit, reaching up to 2 ft tall with a spread of approximately 3 ft. Bolus' Sceptrum produces small, tubular flowers in shades of red, pink, or white.

Leaf size: approximately 4 inches.

Water a young or newly planted Bolus' Sceptrum 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.

Bolus' Sceptrum thrives in full sun to partial shade.

Paranomus bolusii tolerates temperatures of 50–80°F. Bolus' Sceptrum prefers humidity levels of 40–70%.

Well-draining, acidic soil mix with sand and peat moss. Good drainage is essential for Bolus' Sceptrum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Bolus' Sceptrum 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, acidic soil mix with sand and peat moss. Avoid low spots where water collects after rain.

Bolus' Sceptrum 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.

Bolus' Sceptrum can spread to about 3 ft (0.9 m) and reach about 2 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 Bolus' Sceptrum 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.

Bolus' Sceptrum 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.

Bolus' Sceptrum can be propagated through seeds, cuttings. Similar propagation techniques also apply to wild rosemary plant care, which shares the same genus.

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

Bolus' Sceptrum grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Bolus' Sceptrum is native to the Western Cape, South Africa. In cooler regions, grow Bolus' Sceptrum as a houseplant or bring it indoors before the first frost.
