The male flowers are more attractive and are noted for the way in which the pollinia are fired out of the flowers if the sensitive triggers are touched. Growing catasetums should be no more difficult than growing your other orchids or house plants which like warm temperatures and lots of light. In their native habitat they generally experience a dry period of several months. During this period the plants lose their leaves and are dormant. They can be killed very rapidly by over watering when in a leafless condition.
Death seems to happen almost overnight.
If in doubt, no leaves, no water, is probably safer. I regularly forced my plants into dormancy by cutting off any remaining leaves in November. Catasetums will do well in a variety of potting media so long as they are fertilized and watered regularly. To simplify your watering requirements it is probably best to use the potting medium which has been used for your other orchids. Sphagnum moss works well for most people.
