Some more good info
here.
Usually, from my experience, often there are contradicting cultural info across several sources. In this case, what I've found in Orchidwiz and IOSPE is that it's a cold to cool growing which might indicate high altitude habitats. What I found in wiki, is that it grows from sea level to 2.500m.
what do you mean by hotter temps?
As a side note, these are tubers which mean they spend part of their life cycle bellow the surface unnoticed.
