This species is the northernmost-occurring epiphytic orchid in terms of latitude in the New World (maybe worldwide). It appears there are at least two forms of this species, a southerly form from Florida and Mexico and a more northerly form that is native to Louisiana and the Gulf Coast. This form seems to be less robust in terms of bloom and plant size but is also extremely cold-tolerant. My plant is a division of a piece that was rescued off a magnolia tree set to be cut down. This is the first "presentable" blooming I've gotten.
