Which are the decidous Phals?
 

I have a couple of Phal species that have dropped their leaves. I don't
remember which of these it is normal and which of these are just dead.
Roots look ok on some of them...others could go either way.

minus
lowii
wilsonii (although it didn't go completely leafless and I see new growth)

Anyone have this info at hand? (I guess I could crack the book open and
look it up but I'm basically lazy).

Good Growing,
Gene
