Tillandsia usneoides - Spanish Moss Bromeliaceae Wayne Roderick, Orinda It isn't Spanish and it isn't a moss, but rather a member of the pineapple family growing over a wide range from the southeastern U.S. to northern South America. Wayne keeps his in his green house; mine is on supports on the north side of the house. It forms single flowers well hidden in the foliage. Wayne's were 0.25-inches across and straw-colored; mine are no larger, but pea green. A form from Venezuela is more robust but doesn't grow well -- probably too cool nights.
