Pectocarya penicillata Plant Care

Pectocarya penicillata (Pectocarya penicillata) belongs to the Boraginaceae family within the Pectocarya genus. Pectocarya penicillata is native to much of western North America from British Columbia to Wyoming to Baja California.

Pectocarya penicillata displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Pectocarya penicillata produces small white or purple flowers in clusters.

Leaf size: approximately 1.5 inches.

Water a young or newly planted Pectocarya penicillata 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.

Pectocarya penicillata thrives in full sun to partial shade.

Pectocarya penicillata tolerates temperatures of 50–85°F. Pectocarya penicillata prefers humidity levels of 30–60%.

Well-draining sandy soil with low to moderate fertility. Good drainage is essential for Pectocarya penicillata to prevent waterlogging, which leads to root rot and fungal issues.

Feed Pectocarya penicillata 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and well-draining sandy soil with low to moderate fertility. Avoid low spots where water collects after rain.

Pectocarya penicillata 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.

Pectocarya penicillata can spread to about 1 ft (0.3 m) and reach about 1 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 Pectocarya penicillata 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.

Pectocarya penicillata 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.

Pectocarya penicillata can be propagated through seeds. Similar propagation techniques also apply to pectocarya heterocarpa plant care, which shares the same genus.

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

Pectocarya penicillata grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Pectocarya penicillata is native to much of western North America from British Columbia to Wyoming to Baja California. In cooler regions, grow Pectocarya penicillata as a houseplant or bring it indoors before the first frost.
