Ludisia discolor var. ordiana

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

The ordiana variety stands out for its foliage pattern; its care is the same as that of the typical form.

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

Water frequently, but allow the top layer of the substrate to dry out between waterings. Do not leave water in the saucer or decorative cover pot. 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, without leaving the plant completely dry for weeks.

Choose a slightly shallow, wide pot with good drainage. The substrate should be airy, with moderate moisture retention. A suitable option is substrate for Ludisia, Vanilla and Paphiopedilum. Repot when new roots appear or when the mix begins to break down. It is easily propagated 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 extreme drying. It does not have to flower to be a good plant: many people grow it for its foliage; the flowers are a bonus.
