Potentilla basaltica Plant Care

Potentilla basaltica (Potentilla basaltica) belongs to the Rosaceae family within the Potentilla genus. Potentilla basaltica is native to a small area of the Modoc Plateau and Warner Mountains in northeastern California and northwestern Nevada.

Potentilla basaltica displays a low spreading shrub growth habit, reaching up to 1.5 ft tall with a spread of approximately 2 ft. Potentilla basaltica produces small, bright yellow flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Potentilla basaltica 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.

Potentilla basaltica thrives in full sun to partial shade.

Potentilla basaltica tolerates temperatures of 50–75°F. Potentilla basaltica prefers humidity levels of 40–60%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Potentilla basaltica to prevent waterlogging, which leads to root rot and fungal issues.

Feed Potentilla basaltica 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 loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Potentilla basaltica 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.

Potentilla basaltica can spread to about 2 ft (0.6 m) and reach about 2 ft (0 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Potentilla basaltica 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.

Potentilla basaltica 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.

Potentilla basaltica can be propagated through softwood cuttings, division. Similar propagation techniques also apply to golden cinquefoil plant care, which shares the same genus.

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

Potentilla basaltica grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Potentilla basaltica is native to a small area of the Modoc Plateau and Warner Mountains in northeastern California and northwestern Nevada. In cooler regions, grow Potentilla basaltica as a houseplant or bring it indoors before the first frost.
