Ludisia discolor 'Red Velvet' (jewel orchid)

Ludisia discolor 'Red Velvet' (jewel orchid) is a selection of the jewel orchid Ludisia discolor, a terrestrial (occasionally 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, often reddish, and 20–25 cm long; 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 'Red Velvet' selection retains the velvety foliage in deep red shades typical of the jewel orchid.

It 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 needs moving air: stagnant air combined with wet leaves increases the risk of leaf spots. High humidity is beneficial, 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 cachepot. From autumn onward, gradually reduce the 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 at a time.

Choose a slightly shallow, wide pot with good drainage. The substrate should be loose and have moderate water 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 propagates easily from stem cuttings in moderate warmth and stable humidity.

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