Katuk (Sauropus androgynus) is a shrub, indigenous to Southeast Asia that is cultivated in Cambodia, Indonesia, Laos, Malaysia, the Philippines, Thailand, Vietnam and India. It thrives in tropical climates in lowland rainforests where it grows between 4-6 feet tall. Additional Katuk plant info describes it as an upright bush with multiple stems and dark green, oval shaped leaves. In tropical climates, the plant stays green year round, but in cooler climes, the bush will likely lose leaves in the winter only to regrow in the spring. The shrub blooms in the summer and fall with small, flat, round, yellow to red flowers in the leaf axil followed by a purple fruit with tiny black seeds. It takes two Katuk shrubs to pollinate and produce fruit.
