Her is a good example of the color change of my Neofinetia falcata x Vanda tessellata v. alba. The paler flower was a summer bloom and the more colorful is a current bloom that was subjected to several night temperatures in the fifties and lower sixties with a couple of forties thrown in for good measure.
That is certainly a very interesting post but it is too much splitting atoms for me. I will take whatever I get in the way of a walkeriana flower and like it.
I wonder if there is a descriptive thread somewhere about the scents.
