Camille, Catasetinae are very easy to grow! They only need a lot of light (Cattleya or higher) and lots of water and fertilizer during the growing season. Important: DO NOT WATER before the new growth has roots of at least 5 cm long!
Schwerter has currently some very nice Catasetinae! If you order I would recommend to get Catasetum pileatum "Green Gold", as it is normally not easily found in Europe ('Oro Verde' is much easier to get, and probably cheaper in France!)... ok, it is more expensive than 'Oro Verde', but if you can get it, do it

The plant is very nice and can be blooming next year!
