Fragrant rushfoil Plant Care

Fragrant rushfoil (Heterochaenia fragrans) belongs to the Campanulaceae family within the Heterochaenia genus. Fragrant rushfoil is native to the island of Réunion, Mascarene Islands. Fragrant rushfoil is also known as Sweet-scented heterochaenia.

Fragrant rushfoil displays a spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Fragrant rushfoil produces small bell-shaped flowers in shades of blue, purple, or white.

Leaf size: approximately 2 inches.

Water a young or newly planted Fragrant rushfoil every 3–5 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.

Fragrant rushfoil thrives in partial shade to full shade. The optimal light range is 50–500 lux. Avoid placing Fragrant rushfoil in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Heterochaenia fragrans tolerates temperatures of 50–75°F. Fragrant rushfoil prefers humidity levels of 40–70%.

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Fragrant rushfoil to prevent waterlogging, which leads to root rot and fungal issues.

Feed Fragrant rushfoil 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 partial shade to full shade and well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Fragrant rushfoil 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.

Fragrant rushfoil can spread to about 2 ft (0.5 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Fragrant rushfoil 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.

Fragrant rushfoil 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.

Fragrant rushfoil can be propagated through seeds, division of rhizomes. Similar propagation techniques also apply to bourbon daisy plant care, which shares the same genus.

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

Fragrant rushfoil grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Fragrant rushfoil is native to the island of Réunion, Mascarene Islands. In cooler regions, grow Fragrant rushfoil as a houseplant or bring it indoors before the first frost.
