Hi John,
I don't remember exactly what the cross is. But I know one of its parents is Paph. rothschildianum. Let me check the name tag and get back to you.
The central highlands explains alot about where and how
you grow such beautiful Phrags. I have a dear friend in
Kuching, Borneo who has tried very hard to grow Phrags.
and the heat just wears them down and they die. Monsoon season doesn't help much either since he grows
outside in trees and a small shade house.
