Sobralia callosa

I accidentally bloomed mine once. One flower on a 20+ growth plant.

Hope that helps.

 

When I posted that in November, I moved my plant to a "do or die" kind of situation; I set it on a pot of laelia anceps that blooms regularly for me. Bright light, big temp swings, etc. My 30ish growth plant has at least 5-8 buds forming. Prolly death spikes, but at least it's gonna flower.

It also has some new death leads...

 

My whole greenhouse gets kind of dry in the winter. Mostly because I find it's hard to keep it warm enough, and cool + moist = bad news. Not to say there's much of a pronounced dryness out there, but it's definitely not as wet as in the summer.
