Sundanese stylo Plant Care

Sundanese stylo (Stylosanthes sundaica) belongs to the Fabaceae family within the Stylosanthes genus. Sundanese stylo is native to the New World Tropics, and widely introduced as a forage to the tropics of Africa, India, Southeast Asia, Malesia, and Australia. Sundanese stylo is also known as Townsville stylo, Stylosanthes humilis.

Sundanese stylo displays a low-growing spreading perennial growth habit, reaching up to 2 ft tall with a spread of approximately 2 ft. Sundanese stylo produces small clusters of yellow, orange, or red flowers.

Leaf size: approximately 4 inches.

Stylosanthes sundaica requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Sundanese stylo thrives in full sun to partial shade.

Stylosanthes sundaica grows best at temperatures of 65–85°F. Sundanese stylo prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added organic matter. Good drainage is essential for Sundanese stylo to prevent waterlogging, which leads to root rot and fungal issues.

Feed Sundanese stylo every month during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Repot every 1-2 years in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Sundanese stylo can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to pencil flower plant care, which shares the same genus.
