Hairy Indigo Plant Care

Hairy Indigo (Indigofera hirsuta) belongs to the Fabaceae family within the Indigofera genus. Hairy Indigo is native to nearly all the world's tropics. Hairy Indigo is also known as Hairy Bush Clover.

Hairy Indigo displays an upright, spreading shrub growth habit, reaching up to 4 ft tall with a spread of approximately 6 ft. Hairy Indigo produces showy clusters of pink, purple, or white pea-like flowers.

Leaf size: approximately 3 inches.

Water a young or newly planted Hairy Indigo 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.

Hairy Indigo thrives in full sun to partial shade.

Indigofera hirsuta tolerates temperatures of 50–85°F. Hairy Indigo prefers humidity levels of 40–70%.

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

Feed Hairy Indigo 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 full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Hairy Indigo 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.

Hairy Indigo can spread to about 6 ft (1.8 m) and reach about 4 ft (1 m) tall. Space plants about 6 ft (1.8 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Hairy Indigo 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.

Hairy Indigo 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.

Hairy Indigo can be propagated through seeds, softwood cuttings. Similar propagation techniques also apply to indigofera astragalina plant care, which shares the same genus.

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

Hairy Indigo grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Hairy Indigo is native to nearly all the world's tropics. In cooler regions, grow Hairy Indigo as a houseplant or bring it indoors before the first frost.
