I'll admit to not even knowing what "Hwra" is even an abbreviation for. I received a seedling as a gift (always nice), from a sister who knows I like orchids (but who doesn't know enough about them to realize there are LOTS of different kinds).
My search of the internet revealed some great photos and that it is a cross of Leochilus, oncindium and Rodriguezia. Some sites said to grow it like a phal.
Any advice that is more specific?
