Chaparral Pea Plant Care

Chaparral Pea (Pickeringia montana) belongs to the Fabaceae family within the Pickeringia genus. Chaparral Pea is native to California. Chaparral Pea is also known as False Lupine, Xylothermia montana.

Chaparral Pea displays a spreading shrub growth habit, reaching up to 4 ft tall with a spread of approximately 6 ft. Chaparral Pea produces small clusters of white to pink pea-like flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Chaparral Pea every 7–14 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.

Chaparral Pea thrives in full sun to partial shade.

Pickeringia montana tolerates temperatures of 50–85°F. Chaparral Pea prefers humidity levels of 40–70%.

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

Feed Chaparral Pea 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.

Chaparral Pea 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.

Chaparral Pea 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 Chaparral Pea 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.

Chaparral Pea 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.

Chaparral Pea can be propagated through seeds, root cuttings.

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

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