Found in Antioquia Colombia at elevations around 2500 meters as a cold, not cool grower. A look alike that is commonly sold as lunaris, is characterized by a longer, more slender flower. I got mine from Andy so I assume it is the real one. Lunaris of course refers to the round, moon like flower of the true lunaris.
