Irises. The number and kinds of Irises that will grow in Florida is limited by climate conditions. However... Blooming so far in 2015.
Iris albicans. This is the only bearded Iris I have had real success with. It increases well, but has to be grown in a pot with potting soil.
Iris tectorum Alba. Mixed results but looks promising.
Iris virginica. Don't let it get too dry.
