The fan gets pretty far advanced before the roots start. And then the roots have to develop (while the fan finishes maturing) before the flower starts. So that makes all of these rather slow relative to many other orchids. The results are worth the wait, you just need an extra bit of patience (over and above the patience that all orchids require
) For the multiflorals, the process can take 3 years or more. Most of the other types of Paphs are a little quicker but none of them are exactly jackrabbits.
