Velvet Leaf Senna Plant Care

Velvet Leaf Senna (Senna gaudichaudii) belongs to the Fabaceae family within the Senna genus. Velvet Leaf Senna is native to some Pacific Islands including Hawaii, parts of Southeast Asia and Queensland in Australia. Velvet Leaf Senna is also known as Gaudichaud's Senna.

Velvet Leaf Senna displays an upright, spreading shrub growth habit, reaching up to 5 ft tall with a spread of approximately 5 ft. Velvet Leaf Senna produces bright yellow, pea-like flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Velvet Leaf Senna every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Velvet Leaf Senna thrives in full sun to partial shade.

Senna gaudichaudii tolerates temperatures of 60–85°F. Velvet Leaf Senna prefers humidity levels of 40–70%.

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

Feed Velvet Leaf Senna every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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 full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Velvet Leaf Senna is suited to USDA Zone 10a – 12b.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Velvet Leaf Senna can spread to about 5 ft (1.5 m) and reach about 5 ft (2 m) tall. Space plants about 5 ft (1.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Velvet Leaf Senna 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 tree in one year.

Velvet Leaf Senna 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 Leaf Senna can be propagated through seeds, softwood cuttings. Similar propagation techniques also apply to alexandrian senna plant care, which shares the same genus.

Velvet Leaf Senna is susceptible to aphids, caterpillars, 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 Leaf Senna grows outdoors in USDA Zone 10a – 12b. It survives winters down to planting zone 10a. Velvet Leaf Senna is native to some Pacific Islands including Hawaii, parts of Southeast Asia and Queensland in Australia. In cooler regions, grow Velvet Leaf Senna as a houseplant or bring it indoors before the first frost.
