Masdevallia pachyantha is a delightful miniature Masdevallia endemic to Colombia where it grows in cool cloud forests from 2900 to 3600m. This is a higher altitude than that of many of the Masdevallias we grow and so we keep Masdevallia pachyantha on lower shelves in the greenhouse to avoid heat stress, although we have not noticed adverse affects in any of the past three summers.
Our cloud forest greenhouse where we keep our Masdevallias has a minimum temperature of 12C and in the summer is shaded with two or three layers of green 40% shade net. We water pots at least every other day and so plants are never allowed to dry out completely.
Flowers last approximately a month and have a rather pleasent fruity smell.
