Fun Facts
- 🌱 Spathoglottis unifiora is one of the easiest terrestrial orchids to grow and is often recommended as a beginner's orchid, unlike many temperamental tropical orchid species.
- 🌱 The genus Spathoglottis contains about 50 species, mostly from Southeast Asia, and the name derives from Greek words meaning 'spathe' (a bract) and 'glottis' (tongue), referring to the flower's shape.
- 🌱 Unlike epiphytic orchids that grow on trees, Spathoglottis species are terrestrial and grow in the ground with pseudobulbs that help them survive periods of drought by storing water and nutrients.
