Hauya elegans subsp. cornuta Plant Care

Hauya elegans subsp. cornuta (Hauya elegans subsp. cornuta) belongs to the Onagraceae family within the Hauya genus.

Hauya elegans subsp. cornuta displays an upright, spreading shrub growth habit, reaching up to 3 ft tall with a spread of approximately 4 ft. Hauya elegans subsp. cornuta produces showy, tubular flowers in shades of pink, purple, or white.

Leaf size: approximately 6 inches.

Water a young or newly planted Hauya elegans subsp. cornuta 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.

Hauya elegans subsp. cornuta thrives in full sun to partial shade.

Hauya elegans subsp. cornuta tolerates temperatures of 60–80°F. Hauya elegans subsp. cornuta prefers humidity levels of 40–70%.

Well-draining, fertile soil with high organic content. Good drainage is essential for Hauya elegans subsp. cornuta to prevent waterlogging, which leads to root rot and fungal issues.

Feed Hauya elegans subsp. cornuta 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, fertile soil with high organic content. Avoid low spots where water collects after rain.

Hauya elegans subsp. cornuta is suited to USDA Zone 13a.

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.

Hauya elegans subsp. cornuta can spread to about 4 ft (1.2 m) and reach about 3 ft (1 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Hauya elegans subsp. cornuta 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.

Hauya elegans subsp. cornuta is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Hauya elegans subsp. cornuta can be propagated through seeds, division of clumps. Similar propagation techniques also apply to hauya elegans plant care, which shares the same genus.

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

Hauya elegans subsp. cornuta grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Hauya elegans subsp. cornuta as a houseplant or bring it indoors before the first frost.
