What is Katuk?

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 (1 to 2 m.) 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.

Katuk Plant Info

Growing a Katuk shrub is relatively easy, provided you live in an area of moist, hot conditions or can mimic such conditions in a greenhouse. When growing a Katuk shrub, it will do best in a shaded area, just like the understory of the rainforest it is native to, but it will also do well in full sun provided you keep the soil damp. Katuk is easily propagated via cuttings set in water or put directly into the soil in a moist shady area. Apparently, the shrub can grow up to a foot (0.5 m.) a week in ideal conditions, although it has a tendency to flop over when it gets too tall. For this reason and to encourage tender new shoots, regular pruning is done by Asian cultivators. This shrub seems to be remarkably pest-free.
