Catasetum's are very easy to grow and flower, Donna Wise is Ctsm. tenebrosum (a species) crossed with Ctsm. Orchidglade (Ctsm. pileatum x Ctsm. expamsum). I grow them in plastic octagonal basquets on medium sized orchid mix and hang them quite high on the greenhouse so it gets quite high light. In case you did not know, catasetums bloom male or female flowers depending on the light. Male flowers are considered more attractive (?). Water them a lot when in active grow and fertilize every 2-4 weeks. A relative rest is useful when growing ends, just keep down the water and fertilizer. Pests are not usually a problem and if some I just wipe the leaves with some diluted alcohol. Happy growing!
