Spanish Moss is probably the most common Air Plant.
The botanical name is Tillandsia usneoides.
I shot this photos at greenhouse.
Spanish moss (Tillandsia usneoides) is an epiphytic flowering plant that often grows upon larger trees in tropical and subtropical climates, native to much of Mexico, Bermuda, the Bahamas, Central America, South America, the southern United States, and the West Indies as well as being naturalized in Queensland (Australia) known as "grandpas beard" and in French Polynesia.
