Peninsular Navarretia Plant Care

Peninsular Navarretia (Navarretia peninsularis) belongs to the Polemoniaceae family within the Navarretia genus. Peninsular Navarretia is native to southern California and Baja California. Peninsular Navarretia is also known as Peninsular pincushionplant.

Peninsular Navarretia displays a low-growing mat-forming growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Peninsular Navarretia produces small colorful tubular flowers in clusters.

Leaf size: approximately 1 inches.

Water a young or newly planted Peninsular Navarretia 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.

Peninsular Navarretia thrives in full sun to partial shade.

Navarretia peninsularis tolerates temperatures of 50–80°F. Peninsular Navarretia prefers humidity levels of 40–60%.

Well-draining sandy soil with added organic matter for moisture retention. Good drainage is essential for Peninsular Navarretia to prevent waterlogging, which leads to root rot and fungal issues.

Choose a spot with full sun to partial shade and well-draining sandy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Peninsular Navarretia 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.

Peninsular Navarretia 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 Peninsular Navarretia 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.

Peninsular Navarretia 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.

Peninsular Navarretia can be propagated through seeds. Similar propagation techniques also apply to pine-brush plant care, which shares the same genus.

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