Streptanthus drepanoides Plant Care

Streptanthus drepanoides (Streptanthus drepanoides) belongs to the Brassicaceae family within the Streptanthus genus. Streptanthus drepanoides is native to California.

Streptanthus drepanoides displays an upright, branching growth habit, reaching up to 1.5 ft tall with a spread of approximately 1 ft. Streptanthus drepanoides produces small, tubular flowers in shades of purple, pink, or white.

Leaf size: approximately 3 inches.

Water a young or newly planted Streptanthus drepanoides 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.

Streptanthus drepanoides thrives in full sun to partial shade.

Streptanthus drepanoides tolerates temperatures of 50–80°F. Streptanthus drepanoides prefers humidity levels of 40–60%.

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

Feed Streptanthus drepanoides 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.

Streptanthus drepanoides 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.

Streptanthus drepanoides can spread to about 1 ft (0.3 m) and reach about 2 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 Streptanthus drepanoides 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.

Streptanthus drepanoides 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.

Streptanthus drepanoides can be propagated through seeds. Similar propagation techniques also apply to streptanthus anceps plant care, which shares the same genus.

Streptanthus drepanoides is susceptible to aphids, cabbage worms, flea beetles. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Streptanthus drepanoides grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Streptanthus drepanoides is native to California. In cooler regions, grow Streptanthus drepanoides as a houseplant or bring it indoors before the first frost.
