Narrow-leaf guichenotia Plant Care

Narrow-leaf guichenotia (Guichenotia angustifolia) belongs to the Malvaceae family within the Guichenotia genus. Narrow-leaf guichenotia is native to the south-west of Western Australia. Narrow-leaf guichenotia is also known as Slender-leaf guichenotia.

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

Leaf size: approximately 2 inches.

Water a young or newly planted Narrow-leaf guichenotia 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.

Narrow-leaf guichenotia thrives in full sun to partial shade.

Guichenotia angustifolia tolerates temperatures of 50–85°F. Narrow-leaf guichenotia prefers humidity levels of 40–60%.

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

Feed Narrow-leaf guichenotia 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 full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Narrow-leaf guichenotia 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.

Narrow-leaf guichenotia 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 Narrow-leaf guichenotia 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.

Narrow-leaf guichenotia 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.

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

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

Narrow-leaf guichenotia grows outdoors in USDA Zone 9a – 11a. It survives winters down to planting zone 9a. Narrow-leaf guichenotia is native to the south-west of Western Australia. In cooler regions, grow Narrow-leaf guichenotia as a houseplant or bring it indoors before the first frost.
