Spanish moss always reminds me so much of the south and of Walterboro!
"Tillandsia usneoides (S. E. United States to Argentina and Chile) ... growing from trees as silvery-gray threadlike masses to 25 ft. long, densely covered by the gray scales which are a means of receiving and holding atmospheric moisture, and which help to enable the plant to dispense with roots; small axial flowers with petals 3/8 in. (1 cm) long, in changing colors yellowish-green to blue."
Native Americans called the plant "tree hair", which name the French explorers turned to "Barbe espagnole" -- "Spanish Beard" -- to insult their bitter rivals in the New World. The Spanish retorted with "Cabello francés" ("French hair").
"Spanish Moss", a milder variation of the French taunt, has survived. Another common name is "Graybeard".
