Sonerila dongii, a recently described species native to the Lam Dong province in Vietnam, is notable for its unique chocolate-brown mottling on lime green foliage and vibrant pink flowers. This member of the Melastomataceae family is relatively easy to care for indoors, especially compared to other Sonerila species, which are often more delicate. Its compact, succulent growth habit and striking foliage make it a good candidate for terrariums or carefully humidified environments.

Native to

Sonerila dongii is native to the high-humidity tropical forests of southern Vietnam. These origins contribute to its preference for moist, well-drained soil and consistently high humidity, which should be replicated indoors for optimal growth.

Water

Sonerila dongii requires a balance of moisture, with a preference for evenly moist soil. Water moderately, allowing the top layer to dry slightly between waterings to avoid root rot. Since it’s somewhat succulent, avoid overwatering, particularly in lower light or cooler conditions.

Light

This plant thrives in bright, indirect light. It can tolerate low light but may exhibit richer leaf coloration with higher light levels, provided it’s filtered to avoid direct sun, which can scorch the leaves. Ideal placement would be near an east or north-facing window or under a grow light if natural light is insufficient.

Humidity

High humidity, ideally above 60%, is essential for Sonerila dongii, making it well-suited for a terrarium environment. Alternatively, place it near a humidifier or use a pebble tray to maintain consistent humidity around the plant, especially in dry indoor climates.

Temperature

This plant prefers warm temperatures ranging from 18-26°C (65-79°F) and does not tolerate cold well. It should be kept away from drafts and sudden temperature drops, as these can cause stress and slow its growth.
