While many Microcoelia and other leafless orchids need tropical warmth and humidity, Microcoelia stolzii is easy to grow under a wider range of conditions. Mine lives on the patio, relatively shady. It gets daily watering in summer, every two days in winter along with everything else that grows in that area. It seems to be growing better for me since I started using RO water in that area, but it grew and bloomed before that, when it got city water. You can see in the last photo that it has developed a rather robust system of roots. In the absence of leaves, it depends on the chlorophyll in the roots (the green that is visible when the roots are wet) for the photosynthesis to sustain itself.
It is native to a wide range of central and eastern Africa, at elevations from 800 to 2450 m.
