Description

Malvaviscus arboreus, commonly known as Turk's Cap, is a small to medium-sized shrub with distinctive, bright red, funnel-shaped flowers that resemble a cap. The blooms are often seen in clusters and are attractive to hummingbirds and butterflies. The plant has lush, dark green leaves and a bushy growth habit, making it ideal for ornamental use in gardens, borders, and as a hedge. It can tolerate pruning and is often shaped as a rounded shrub or small tree. Turk's Cap is well-suited for tropical and subtropical climates and adds vibrant color to landscapes year-round.

Light requirements

Turk's Cap thrives in full sun to partial shade. While it will grow in partial shade, flowering will be most prolific in full sunlight. It can tolerate some light shade, especially in hotter climates, but will produce more blooms in sunny locations. Aim for at least 4 to 6 hours of direct sunlight daily for the best results.

Soil preferences, including pH and drainage

Malvaviscus arboreus prefers well-draining, slightly acidic to neutral soil with a pH between 6.0 and 7.0. It can tolerate a range of soil types, including sandy or loamy soils, as long as they provide good drainage. Poorly drained soils can lead to root rot, so it's important to ensure the soil allows water to flow through freely. If growing in containers, use a well-draining potting mix designed for shrubs.

Water needs

This plant is moderately drought-tolerant once established but benefits from regular watering during its active growing season. Water the plant deeply when the soil feels dry to the touch, but be sure to allow the soil to dry out between waterings to avoid overwatering. During cooler months, reduce watering as the plant’s growth slows. Turk's Cap prefers consistently moist soil but can handle short periods of dryness.
