Masdevallia erinacea
This miniature orchid has flowered and multiplied continuously once I brought it home and gave it stable humidity. I have been able to divide it and grow it in a variety of conditions very quickly which makes me feel as if this particular masdevallia standout from it's peers.
Masdevallia have a tendency to be fussy, but this one takes cool to warm temperatures. As warm as what is typically expected of bulbophyllums! It will even tolerate lower humidity than other masdevallias. Pictured below in the comments is yet another division that didn't make it into the video. It is potted in a miniature glazed terracotta vase with tree fern fiber, charcoal and perlite and sits on a shelf with relative room humidity of around 55-60%. It is important to note that while it tolerates this treatment, it does not grow as quickly or vigorously as it would in higher humidity levels.
