Notes

Perennial herbs. Infralittoral zone (NLSS−LW, NLSM−LWP). Jun−Aug. This exotic, invasive taxon is native to warm climates of the Old World. Hydrilla verticillata was introduced to Florida in 1950 as an ornamental and has since become a terrible aquatic invasive throughout the Southeast. Where introduced, H. verticillata chokes out native submersed aquatic vegetation (e.g., Ceratophyllum , Myriophyllum , Najas , Potomogeton , Vallisneria ), negatively impacts recreational activities and alters natural hydrology and water chemistry ( Ramey and Peichel 2001).
