Wildlife:
Attracts butterflies and bees. Documented bee visitors include Hylaeus schwarzi, Dianthidiuin floridiense, Ceratina dupla floridaiza, Apis inellifera , and Xylocopa inicaizs (Deyrup et al. 2002).
Ducks love the plants and a risk is that they might devour an entire planting.

General Comments:
The natural range in Florida appears to include the entire mainland and exclude the Florida keys. Herbarium specimen in the Florida Keys was in a man-made pond leading to the suspicion that the plant was brought in by man and that the keys are not within the natural range of the species. The counties where the plant has not been documented are well within the range of the species and have ample habitats to support this common species (this author has seen it in most of those counties).
