According to the Baker's culture sheet, in nature they see 54°-58° nights and 74°-79° days, consistently all year. There is even a statement "Growers indicate that plants do poorly if grown in continuously warm conditions."

Bummer. I was really hopeful that wasn’t the case. I don’t really have much in the way of indoor growing space to put this either. I’m now seeing there is two different populations of these, too. One that grows at 1500-1900m in New Guinea. The other on the surrounding islands at 150-700m. I can usually grow things that come from the latter but orchids from former can be a bit hit and miss. Smh...

I WISH this thing grew like my atroviolaceum! The only time I have had issues with any of my Latourias has been when I let them get too dry for their liking. That’s when I would normally see that sort of browning and eventual leaf tip die back. I did not have this particular polysema over the winter but I suppose if I have been growing it too hot the rest of the year, like Ray mentioned, I’ve probably been weakening it beyond repair
