Aliciella subnuda Plant Care

Aliciella subnuda (Aliciella subnuda) belongs to the Polemoniaceae family within the Aliciella genus. Aliciella subnuda is native to the Colorado Plateau and Canyonlands region of the southwestern United States.

Aliciella subnuda displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Aliciella subnuda produces small, tubular flowers in shades of pink, purple, or white.

Leaf size: approximately 2 inches.

Water a young or newly planted Aliciella subnuda 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.

Aliciella subnuda thrives in full sun to partial shade.

Aliciella subnuda tolerates temperatures of 50–80°F. Aliciella subnuda prefers humidity levels of 30–60%.

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

Feed Aliciella subnuda 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 added organic matter for moisture retention. Avoid low spots where water collects after rain.

Aliciella subnuda 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.

Aliciella subnuda 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 Aliciella subnuda 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.

Aliciella subnuda 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.

Aliciella subnuda can be propagated through seeds, division of clumps. Similar propagation techniques also apply to aliciella caespitosa plant care, which shares the same genus.

Aliciella subnuda 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.

Aliciella subnuda grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Aliciella subnuda is native to the Colorado Plateau and Canyonlands region of the southwestern United States. In cooler regions, grow Aliciella subnuda as a houseplant or bring it indoors before the first frost.
