Boechera perennans Plant Care

Boechera perennans (Boechera perennans) belongs to the Brassicaceae family within the Boechera genus. Boechera perennans is native to the southwestern United States and northern Mexico.

Boechera perennans displays a low rosette, clumping growth habit, reaching up to 0.5 ft tall with a spread of approximately 0.5 ft. Boechera perennans produces small white or purple flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Boechera perennans 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.

Boechera perennans thrives in full sun to partial shade.

Boechera perennans tolerates temperatures of 50–75°F. Boechera perennans prefers humidity levels of 40–60%.

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

Feed Boechera perennans 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.

Boechera perennans 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.

Boechera perennans can spread to about 1 ft (0.2 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Boechera perennans 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.

Boechera perennans 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.

Boechera perennans can be propagated through seeds, division of clumps. Similar propagation techniques also apply to boechera breweri plant care, which shares the same genus.

Boechera perennans 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.

Boechera perennans grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Boechera perennans is native to the southwestern United States and northern Mexico. In cooler regions, grow Boechera perennans as a houseplant or bring it indoors before the first frost.
