Jim Archibald had seeds from four of his Iranian collections of this species on his seed list last year. One was collected at 1600m and another at 2300m. I saw the species growing in Kazakhstan two years ago at nearer to 3000m on open, rocky slopes. This is an area with heavy species tulip fields. The plant was growing and flowering soon after snow melt. My guess is that it is pretty hardy, although it will probably have good snow cover through the winter and, as it comes from a continental climate, it will not be used to random late frosts.
