No, this plant is not dead

This is Oeceoclades gracillima (also called O. roseovariegata), a miniature orchid from Madagascar.


The plant is quite alive, although its mottled, brown leaves might suggest otherwise. Growing terrestrially among leaf litter, the unusual coloration allows it to blend in to its surroundings, an example of crypsis.


Most species of Oeceoclades (pronounced ee-see-oh-clay-dees) are endemic to Madagascar, an island known for its weird and wonderful flora. O. gracillima hails from dry deciduous forests. The temperature does not vary much annually, but the area endures 6-8 months of seasonal drought, so organisms, like the famous baobab, have had to adapt accordingly. Unlike many other orchids, Oeceoclades spp. can take very little water and are more popular with succulent enthusiasts than orchid growers.

This is the only Oeceoclades I have (for now). I love the patterned leaves and their brown, purple, and black mottling.

O. gracillima is fairly easy to cultivate. A well-draining substrate is important because the thick, fleshy roots are prone to rot. I grow mine in a mix of lava rock, pumice, and fine-grade orchid bark. When actively growing, I water and fertilize regularly. Once the new growth has matured, I hold back on the water, offering just enough to keep the pseudobulbs from shriveling. Intermediate to warm temperatures are fine and the plant can handle low to moderate light. Though not what most people imagine when they hear the word "orchid," I think this understated beauty deserves to be more widely grown.
