: Depending on the species, they may grow as terrestrials in sandy loam, lithophytes on rocky outcrops, or occasionally as epiphytes on floating logs or stumps in swamps. Cultivation and Care
: Recent molecular analysis has expanded the genus to include species that are fully myco-heterotrophic (leafless and relying on fungi for nutrients) as well as traditional photosynthetic types. Distribution and Habitat bletia
The genus Bletia comprises approximately 30 species of terrestrial orchids native to the Americas, ranging from Florida and Mexico down to Argentina. These plants are characterized by subterranean corms, pleated grass-like leaves, and tall flower stalks that produce clusters of cupped, pink to purple blooms. While often confused with the Asian genus Bletilla —which was named in its honor— Bletia is a "New World" genus that thrives in diverse habitats from rocky crevices to swampy woodlands.
