Catasetum expansum is a species of Catasetum found in South America.
Plant blooms from late spring through early winter with several 7.5 cm wide flowers. Flowers are fragrant.
Plant is found growing in the dry forest of northeastern Ecuador at elevations of 20 to 1500 meters
Grow in warm conditions with partially bright light. Water regularly during growing season and when plants drop leaves during dormancy reduce watering. During dormancy only water about twice a month to keep pseudobulbs from shriveling. Resume watering normally when new growths occur in spring. Plants can die easily from over watering. Plants are usually grown in bark with perlite, cork, full sphagnum moss, and tree fern
