Just saw this on a FL Wildflower Foundation post. It was written by Roger Hammer. I had no idea the flowers were fragrant. Now I am going to have to go out at night and sniff.
"Spanish moss (Tillandsia usneoides) isn't rare by any stretch but quite a few people don't realize that it's a bromeliad (Bromeliaceae) related to the pineapple. Even fewer people realize that it actually flowers, and that the blossoms are intensely fragrant at night. If you live in the Deep South where there are old oaks festooned with Spanish moss, the perfume will fill the night air in summer. It blooms from April to August but you have to look close to see the tiny, green flowers."
