Smaller cattleya type species, not hybrids
 

I grow orchids under T5s and I have a Pot. Memoria Irene Feil 'Ruby Red'. It is my only cattleya type orchid. I'm wanting to get some more but they can't grow to be too tall. I would also prefer that they be a different color than pink or purple since I have a lot of orchids that color and that they are a species not a hybrid. Thanks!

I've got a great little Catt. alalorii, which is smaller than most 'mini' hybrids. It comes in a lot of different colors. Other small statured Catts include nobilior, walkeriana, aclandiae, schilleriana and iricolor. There are also a lot of small to mini Laelias. Rupiculous Laelias (liliputiana, milleri, aurea, reginae, etc.) are probably the smallest. If your growing conditions are cool, then you can grow Sophronitis, however Soph. cernua will do well in warmer conditions. There are plenty of other small statured Cattleya types which I've missed, but this should get you started.
