Peliostomum calycinum Plant Care

Peliostomum calycinum (Peliostomum calycinum) belongs to the Scrophulariaceae family within the Peliostomum genus. Peliostomum calycinum is native to Southern Africa.

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

Leaf size: approximately 4 inches.

Water a young or newly planted Peliostomum calycinum 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.

Peliostomum calycinum thrives in partial shade to full shade. The optimal light range is 50–200 lux. Avoid placing Peliostomum calycinum in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Peliostomum calycinum tolerates temperatures of 60–75°F. Peliostomum calycinum prefers humidity levels of 40–60%.

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

Feed Peliostomum calycinum 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 partial shade to full shade and well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Peliostomum calycinum 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.

Peliostomum calycinum 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 Peliostomum calycinum 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.

Peliostomum calycinum 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.

Peliostomum calycinum can be propagated through seeds, division of offsets. Similar propagation techniques also apply to rush-leaved peliostomum plant care, which shares the same genus.

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

Peliostomum calycinum grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Peliostomum calycinum is native to Southern Africa. In cooler regions, grow Peliostomum calycinum as a houseplant or bring it indoors before the first frost.
