Lindy, dont bother with seed propagation. leave it to the experts. Not sure about the Cleisostoma, but with most, germination rates are 0.001% or something like that. as a novice, you will probably muck it up in some way (dont worry, im not trying for that reason)
and be dissapointed. Usually, orchids can take up to 15 years depending on the species to flower, so yea.......just buy some plants and build upon them like most of us have. it is the most efficient way and you actually get to see the flower in most cases.
