Ludisia discolor (jewel orchid) D9

Ludisia discolor, the jewel orchid, is a terrestrial species (occasionally lithophytic) found from northern India to Southeast Asia, including China and Vietnam, in humid forests. It is grown primarily for its velvety leaves, not just 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: 9 cm.

Plants may have leaves with minor cosmetic imperfections.

Requires shade or filtered light, approximately 8,000–10,000 lux, with no direct sunlight on the leaves. Room 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 appropriate.

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 solution after watering, using orchid fertilizer. In winter, if growth slows, reduce watering and fertilizing, but do not leave the plant completely dry for weeks at a time.

Choose a slightly shallow, wide pot with good drainage. The substrate should be loose and have moderate moisture retention. A suitable option is substrate for Ludisia, Vanilla, and Paphiopedilum. Repot when new roots appear or when the mix begins to deteriorate. It is easily propagated from stem cuttings in moderate warmth and stable humidity.

Leaves are most commonly damaged by direct sunlight, water left on the leaves overnight, stagnant air, overwatering, or extreme drying. It does not need to bloom to be a good plant: many people grow it for its foliage; the flowers are a bonus.
