Clowesia (Species and Hybrids) genera, awards, species checklist, slideshow, etc.
Clowesia, originally included in Catasetum, is now a separate genus of seven species. Pendant flower spikes, producing long-lasting and fragrant flowers, form at the base of a pseudobulb. From a genus of moderately sized plants, Clowesias are strong growers that are very resistant to rot. They are similar to Catasetums in cultivation though the blooming cycle is very different, the multiple flower spikes producing flowers in winter to early spring. Repotting should be undertaken after the bloom cycle. In their natural habitat, the 'perfect' flowers with both male and female floral segments would be pollinated by the male euglossine bee. When actively growing, as do the great majority of Catasetinae, Clowesia enjoy moderately bright light, intermediate temperatures and good air movement.
Clowesia are heavy feeders during their growing period but a dry rest period of differing lengths according to species is needed after flowering, specifically, once the plants start to drop leaves. Water is gradually reduced, then withheld. If at all, water sparingly only to prevent pseudobulbs from shrinking too much. Once new growth reaches 4 inches and new roots reach 2 or more inches long, watering is begun, with normal abundant watering taking place once the potting mix again approaches dryness. Fertilize well during the active growing season as the plant does not get a chance to be fertilized during its dry rest period. Clowesia like humidity of 50-70% with warm day temperatures of 75-80 F (24-27 C) dropping 10-15 F (6-8 C) at night. Repot just as new growth is beginning at the end of the dry rest.
