Crown Vetch Plant Care

Crown Vetch (Coronilla varia) belongs to the Fabaceae family within the Coronilla genus. Crown Vetch is native to Africa, Asia and Europe. Crown Vetch is also known as Purple Crown Vetch, Varied Crown Vetch.

Crown Vetch displays a compact, spreading shrub growth habit, reaching up to 3 ft tall with a spread of approximately 4 ft. Crown Vetch produces small, fragrant yellow flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Crown Vetch 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.

Crown Vetch thrives in full sun to partial shade.

Coronilla varia tolerates temperatures of 50–80°F. Crown Vetch prefers humidity levels of 40–60%.

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

Feed Crown Vetch 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.

Crown Vetch 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.

Crown Vetch can spread to about 4 ft (1.2 m) and reach about 3 ft (1 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Crown Vetch 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.

Crown Vetch 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.

Crown Vetch can be propagated through seeds, softwood cuttings. Similar propagation techniques also apply to mediterranean scorpion senna plant care, which shares the same genus.

Crown Vetch 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.

Crown Vetch grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Crown Vetch is native to Africa, Asia and Europe. In cooler regions, grow Crown Vetch as a houseplant or bring it indoors before the first frost.
