Slender Bellflower Plant Care

Slender Bellflower (Guichenotia micrantha) belongs to the Malvaceae family within the Guichenotia genus. Slender Bellflower is native to the south-west of Western Australia. Slender Bellflower is also known as Bluebell Creeper.

Slender Bellflower displays a low, spreading shrub growth habit, reaching up to 2 ft tall with a spread of approximately 3 ft. Slender Bellflower produces showy tubular flowers in shades of pink, purple, or white.

Leaf size: approximately 2 inches.

Water a young or newly planted Slender Bellflower 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.

Slender Bellflower thrives in full sun to partial shade.

Guichenotia micrantha tolerates temperatures of 50–85°F. Slender Bellflower prefers humidity levels of 40–60%.

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

Feed Slender Bellflower 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. Avoid low spots where water collects after rain.

Slender Bellflower is suited to USDA Zone 9a – 11a.

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.

Slender Bellflower 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 Slender Bellflower 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.

Slender Bellflower is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Slender Bellflower can be propagated through seeds, softwood cuttings. Similar propagation techniques also apply to finger flower plant care, which shares the same genus.
