Description and Growing Information

General DescriptionLudisia discolor is a tropical orchid with dark purple-black leaves and small white flowers.
LandscapeOne of the easiest orchids to grow as a houseplant.
CultivationGrow in part shade, in moderately moist, well-drained soil and a warm, humid environment. Intolerant of full sun outdoors in warm weather.

It is best to use tepid water in the morning. Use a balanced fertilizer after watering thoroughly, diluted at quarter to half its strength on a weekly basis.
PestsNo serious pests or diseases of note.
Leaf DescriptionIn basal rosettes at intervals along creeping stems, elliptical, dark green to purple-black with striking gold to red, parallel venation.
