Masdevallia rosea is a very beautiful species from the cloud forests of Colombia, and occurs between 2400 and 3400 m elevation. I have two clones of this species, a “pallida” which is quite a bit easier but nowhere near as nice, and this one, which is pretty unforgiving. In the summer I move it to my wine cooler and it spends the winter in my grow tent, where day temps are in the upper 50s/low 60s and nights are around 50 and occasionally down to the mid 40s. This plant was relentlessly losing new growth since I got it, but recently stabilized and seems quite happy with the winter conditions. This is its first time blooming for me.
