Procumbent Rostellularia Plant Care

Procumbent Rostellularia (Rostellularia procumbens) belongs to the Acanthaceae family within the Rostellularia genus. Procumbent Rostellularia is native to the Indian subcontinent, Indochina, China, Peninsular Malaysia, Sumatra, Java, Sulawesi, the Philippines, Japan, and Korea.

Procumbent Rostellularia displays a low spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Procumbent Rostellularia produces small tubular flowers in shades of pink, purple, or white.

Leaf size: approximately 2 inches.

Water a young or newly planted Procumbent Rostellularia 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.

Procumbent Rostellularia thrives in partial shade to full sun.

Rostellularia procumbens tolerates temperatures of 60–80°F. Procumbent Rostellularia prefers humidity levels of 40–70%.

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

Feed Procumbent Rostellularia 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 sun and well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Procumbent Rostellularia is suited to USDA Zone 8a – 11b.

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.

Procumbent Rostellularia can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Procumbent Rostellularia 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.

Procumbent Rostellularia is hardy down to USDA zone 8a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Procumbent Rostellularia can be propagated through stem cuttings, division, seeds. Similar propagation techniques also apply to rostellularia adscendens plant care, which shares the same genus.

Procumbent Rostellularia 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.

Procumbent Rostellularia grows outdoors in USDA Zone 8a – 11b. It survives winters down to planting zone 8a. Procumbent Rostellularia is native to the Indian subcontinent, Indochina, China, Peninsular Malaysia, Sumatra, Java, Sulawesi, the Philippines, Japan, and Korea.
