Masdevallia coccinea 'Dwarf Pink' is one of the best pink forms and is especially desirable because of its dwarf size and short flower spikes. It also seems to be more tolerant of warmer temperatures than most coccineas. Due to limited growing space it is the only form of Masd. coccinea I grow.
The color of the flowers are affected by temperature with the cooler weather producing deeper colored flowers, but whether the blooms are produced in warmer or cooler temperatures, the flowers fade with age from a deeper to very light pink as is evident from the last picture.
