Ludisia discolor (jewel orchid)

Ludisia discolor, the jewel orchid, is a terrestrial species (sometimes lithophytic) found from northern India to Southeast Asia, including China and Vietnam, in humid forests. It is cultivated mainly for its velvety leaves, not just for its flowers. The stems are fleshy, often reddish, and 20–25 cm long; the elliptic-lanceolate leaves have contrasting white veins against a dark red background. The white flowers, approximately 2 cm across, appear on 10–40 cm flower spikes and usually last 2–3 weeks.

Pot diameter: 12 cm.

Plants may have leaves with minor cosmetic defects.

Requires shade or filtered light, approximately 8,000–10,000 lux, with no direct sunlight on the leaves. Typical indoor temperatures are suitable; avoid radiators and cold drafts. It benefits from air movement: stagnant air combined with wet leaves increases the risk of spotting. High humidity is beneficial, but many plants adapt to moderate humidity if the substrate and ventilation are suitable.

Water frequently, but allow the top layer of the substrate to dry between waterings. Do not leave water in the saucer or decorative cachepot. From autumn onward, gradually reduce the watering frequency. During active growth, fertilize with a diluted orchid fertilizer after watering. In winter, if growth slows, reduce watering and fertilization without leaving the plant dry for weeks at a time.

Choose a slightly shallow, wide pot with good drainage. The substrate should be airy, with moderate water retention. The substrate for Ludisia, Vanilla and Paphiopedilum is suitable. Repot when new roots appear or when the mix begins to break down. It is easy to propagate from stem cuttings in moderate warmth and stable humidity.

The leaves are most often damaged by direct sunlight, water on the leaves in the evening, stagnant air, overwatering or severe drying. It does not need to flower to be a good plant: many people keep it for its foliage; the flowers are a bonus.
