Tillandsia L. is a genus of plant in the family Bromeliaceae (pineapple family). This genus includes more than 700 species, either epiphytes or lithophytes, or terrestrial, present mainly on the American continent (from Florida to Argentina).
Epiphytic or lithophytic tillandsias are sometimes called “air girls” because of their natural propensity to cling wherever conditions permit: telephone wires, tree branches, bark, bare rocks, etc. Their light seeds and equipped with a silky parachute facilitate this dissemination.
Their leaves, more or less silver in color, are covered with specialized cells capable of rapidly absorbing ambient humidity (dew, runoff water). Their roots, when they exist, are transformed into crampons in so-called “aerial” species and only serve as anchors on their support.
