I got an orange one from Parkside Orchids a few years back.
I was told by them and a few AOS judges when asking questions about this species at the Longwood show that this is a tough one to bloom.
Mine is in a hanging 4 inch basket with NewZealand moss.
I water it a bit almost every day because it is not suppose to dry out.
I keep it in indirect sunlight OVER an aircondition vent
I will also put it in the garage daily for an hour or two in the fall season to expose to the lower temp a bit more.
It is a RUSH to successfully bloom this one!
The first time I had three blooms.
The second just one.
I have two blooms coming in now.
These blooms are not fragrant but can last 6 MONTHS!
Gorgeous
