Description

Calliandra haematocephala is a striking, evergreen shrub that is highly prized for its showy, powder-puff-like flowers, white in this variety. These unique, ball-shaped blooms are composed of numerous long, red stamens, which give the plant its distinct, fluffy appearance. It has a bushy, compact growth habit, with fern-like, feathery leaves that add to its ornamental value. This plant is particularly attractive to pollinators, including hummingbirds and butterflies, making it a wonderful addition to wildlife gardens. It is often used in tropical landscapes, where it provides a burst of color and interest throughout the year.

Light requirements

Calliandra haematocephala thrives in full sun to partial shade. It will flower most prolifically when given at least 4 to 6 hours of direct sunlight daily. While it can tolerate some shade, particularly in the afternoon, its flowering may be less abundant in lower light conditions. A sunny spot encourages strong growth and vibrant blooms.

Soil preferences, including pH and drainage

This plant prefers well-draining, slightly acidic to neutral soil (pH 6.0 to 7.0). It thrives in sandy or loamy soils that are rich in organic matter. Good drainage is essential to prevent root rot, so avoid planting in heavy, poorly draining soils. It can tolerate a variety of soil types as long as drainage is adequate, and it does best in moist, well-aerated soil.

Water needs

Calliandra haematocephala requires regular watering to keep the soil evenly moist, especially during the growing season. While it can tolerate some drought once established, it prefers consistent moisture. Ensure the soil does not dry out completely between waterings, but avoid waterlogging, as this can lead to root rot. During the cooler winter months, reduce watering, but keep the soil from becoming too dry.
