About Reichenbach's Masdevallia

Masdevallia reichenbachiana · also called Reichenbach's Masdevallia · tropical

A miniature cool-to-cold growing epiphytic orchid endemic to the wet cloud forests of Costa Rica at 1,500–2,200 m. It produces striking white flowers with deep reddish-purple reverses and yellow tails on erect inflorescences in spring and summer. Exceptionally demanding of cool temperatures and high humidity — best suited to a cool greenhouse.

Preferred mix: Open, fast-draining orchid mix

Watch for — Fungal crown rot: Water pooling in the crown or on leaves in still air causes Fusarium or Botrytis rot. Always water at the base or on the roots, not the crown, and run a fan continuously. Remove affected tissue and treat with a systemic fungicide.
