Butterfly orchid(Encyclia tampensis) is a slow-growing, epiphytic perennial occurring naturally in mesic hammocks, hardwood swamps and mangrove forests. It is most commonly found growing on live oaks, but also occurs on bald cypress, mangroves and pond apples. Its diminutive yet showy flowers appear in late spring and summer; their honey-like fragrance attracts a variety of bees, which are the plant’s primary pollinators.
The flower is comprised of five greenish-brown tepals that surround a white lip with a purple blotch. The plant’s linear– to lanceolate-shaped leaves are evergreen and can grow up to 12 inches long. The fruit is a capsule that is filled with many tiny seeds. Once the capsule opens, the seeds are wind-dispersed.
The genus, Encyclia, is from the Greek enkykleoma, meaning “to encircle.” The species epiphet, tampensis, refers to the city of Tampa, where Encyclia tampensis was first discovered. The common name comes from flower’s resemblance to a butterfly.
