If you are partial to green flowers, you’ll love this orchid!  Angraecum calceolus is a small-sized orchid species from Madagascar, Mauritius, Mozambique, Reunion Islands, and the Seychelles.  This plant is larger than many of the orchid species I’ve listed in my various terrarium planting lists.  Angraecum calceolus is unlikely to be a compatible choice for glass bottle gardens; a more substantially sized terrarium, vivarium, or orchidarium would be required to comfortably accommodate this orchid and provide a suitable home that will present itself as lasting and sustainable accommodation, as the plant develops and matures.
