Katuk (Sauropus androgynus)

Tropical Supergreen with Sweet, Nutty Flavor

Katuk (Sauropus androgynus), also called Sweetleaf or Sayur Manis, is a perennial shrub native to Southeast Asia, India, Malaysia, and the Philippines. Revered for its resilience and utility, Katuk thrives in tropical and subtropical climates, producing edible leaves, shoots, and flowers year-round.

This fast-growing shrub reaches up to 8 feet tall, with dark green leaves and long, pendant branches. In summer and fall, it blooms with white and red flowers that give way to purple fruits with small black seeds—all parts of the plant are edible. Its leaves boast a sweet, nutty flavor and can be eaten raw or cooked, making it a versatile addition to salads, soups, stir-fries, or even as steamed “tropical asparagus.”

Katuk’s nutritional profile is exceptional: its dried leaves contain up to 49% protein and are rich in calcium, iron, vitamins A and C, and antioxidants. Known in Indonesia for enhancing milk flow in breastfeeding mothers, Katuk is as beneficial as it is delicious. Unlike other greens, it tolerates heat without bolting, making it a reliable crop in warmer regions.

Low-maintenance and high-yield, Katuk prefers partial shade but can grow in full sun with consistent watering and damp, well-draining soil. Regular pruning encourages tender new shoots for harvest. Hardy in USDA zones 9-11, it’s a perfect fit for edible gardens and permaculture systems alike.
