Are Paph. sanderianum s particularly difficult to grow?

[Fairorchids]

My post was based on comments by Sam Tsui (Orchid Inn). They were not specific to any specific species, but general for the multi-florals.

He made those comments in connection with a Paph on the show table that night. It was either a Prince Edward of York (roth x sanderianum) or Michael Koopowitz (philippinense x sanderianum).

I have heard the same general comment from Glen Decker (former owner of Piping Rock Orchids), and have grown the few multiflorals I have had accordingly. And yes, they should have a fairly light yellow-green foliage color.
