Common Name The Dark Blue Acacalis
Flower Size 2 1/2" [6.25 cm]
Found in Colombia, Venezuela and Brazil at elevations of 100 to 500 meters as a small sized, hot growing epiphytic and rarely terrestrial plant with fusiform, slightly compressed, rugose pseudobulbs covered with papery bracts and with a single to two coriaceous, oblong-lanceolate, short petiolate leaves, a visible, creeping, slender rhizome and a 12" [30 cm] long, basal, slender inflorescence that is slightly longer than the leaves and arises from the base of a mature pseudobulb and is erect to arching, carries loosely few to several [to 10] showy, fragrant flowers and blooms in the late winter until summer mostly in the late spring. In nature these plants are often found semi-submerged by flooding rivers in the Amazon area with only the flowers above the water line. This orchid will thrive if given a hot, humid environment with lots of shade or dappled sunlight and room for the plant to expand. Daily mistings while in growth are greatly appreciated.
