Wedge-leaf Guinea Flower displays a low spreading shrub growth habit, reaching up to 1.5 ft tall with a spread of approximately 3 ft. Wedge-leaf Guinea Flower produces bright yellow five-petaled flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Wedge-leaf Guinea Flower 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.

Wedge-leaf Guinea Flower thrives in full sun to partial shade.

Hibbertia cuneiformis tolerates temperatures of 50–80°F. Wedge-leaf Guinea Flower prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Wedge-leaf Guinea Flower to prevent waterlogging, which leads to root rot and fungal issues.

Feed Wedge-leaf Guinea Flower 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.

Prune Wedge-leaf Guinea Flower 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.
