Summary

Protea welwitschii, commonly known as cluster-head protea or dwarf savanna sugarbush, is a spreading shrub or small tree native to the bushveld and grasslands of southeastern Africa, including countries like Zimbabwe and Mozambique. It typically grows up to 9.8 feet (3 meters) tall and features elliptic to oblanceolate bluish-green leaves. The plant is notable for its large, showy flower heads that are white to pale cream or brown, blooming from December to May. These flowers are pollinated by beetles and birds, and the species has adapted to survive periodic wildfires, resprouting after being burnt.

Protea welwitschii is valued for its striking flowers and resilience to fire, making it a unique addition to gardens in regions with similar climates. It is often used in ornamental plantings and as a feature in xeriscaping due to its low water requirements. The plant prefers well-drained soils and full sun exposure. While it is generally low-maintenance, it can be susceptible to root rot if overwatered or planted in poorly drained soils. It is also sensitive to frost, which should be considered when planting in cooler climates.CC BY-SA 4.0
