Velvet Groundsel Plant Care

Velvet Groundsel (Stenostomum tomentosum) belongs to the Rubiaceae family within the Stenostomum genus. Velvet Groundsel is native to Jamaica. Velvet Groundsel is also known as Fuzzy Ragwort.

Velvet Groundsel displays an upright, spreading shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Velvet Groundsel produces small, fragrant white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Velvet Groundsel 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.

Velvet Groundsel thrives in filtered sunlight or partial shade. Avoid placing Velvet Groundsel in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Stenostomum tomentosum tolerates temperatures of 65–80°F. Velvet Groundsel prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, acidic soil with high organic matter content. Good drainage is essential for Velvet Groundsel to prevent waterlogging, which leads to root rot and fungal issues.

Feed Velvet Groundsel 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 filtered sunlight or partial shade and well-draining, acidic soil with high organic matter content. Avoid low spots where water collects after rain.

Velvet Groundsel is suited to USDA Zone 10b – 12b.

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.

Velvet Groundsel can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Velvet Groundsel 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.

Velvet Groundsel is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Velvet Groundsel can be propagated through seeds, division of offsets. Similar propagation techniques also apply to stenostomum aromaticum plant care, which shares the same genus.

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

Velvet Groundsel grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Velvet Groundsel is native to Jamaica. In cooler regions, grow Velvet Groundsel as a houseplant or bring it indoors before the first frost.
