Rosulate Navarretia Plant Care

Rosulate Navarretia (Navarretia rosulata) belongs to the Polemoniaceae family within the Navarretia genus.

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

Leaf size: approximately 1 inches.

Water a young or newly planted Rosulate 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.

Rosulate Navarretia thrives in full sun to partial shade.

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

Well-draining sandy soil with added organic matter for moisture retention. Good drainage is essential for Rosulate 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.

Rosulate 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.

Rosulate 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 Rosulate 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.

Rosulate 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.

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

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

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