Calliandra peninsularis Plant Care

Calliandra peninsularis (Calliandra peninsularis) belongs to the Fabaceae family within the Calliandra genus. Calliandra peninsularis is native to Baja California Sur state in Mexico.

Calliandra peninsularis displays a small tree or shrub growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Calliandra peninsularis produces puffball-like clusters of pink or white flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Calliandra peninsularis every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Calliandra peninsularis thrives in full sun to partial shade.

Calliandra peninsularis tolerates temperatures of 60–80°F. Calliandra peninsularis prefers humidity levels of 40–70%.

Well-draining, slightly acidic soil with added organic matter like compost or peat moss. Good drainage is essential for Calliandra peninsularis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Calliandra peninsularis every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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, slightly acidic soil with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Calliandra peninsularis is suited to USDA Zone 9b – 11b.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Calliandra peninsularis can spread to about 8 ft (2.4 m) and reach about 10 ft (3 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Calliandra peninsularis 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 tree in one year.

Calliandra peninsularis is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Calliandra peninsularis can be propagated through seeds, softwood cuttings. Similar propagation techniques also apply to narrowleaf calliandra plant care, which shares the same genus.

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

Calliandra peninsularis grows outdoors in USDA Zone 9b – 11b. It survives winters down to planting zone 9b. Calliandra peninsularis is native to Baja California Sur state in Mexico. In cooler regions, grow Calliandra peninsularis as a houseplant or bring it indoors before the first frost.
