Hydrilla is an aquatic plant native to Asia, Africa, and Australia. Hydrilla produces tiny white flowers on long stalks. Hydrilla plants can grow up to one inch per day during their peak growing periods and can double their biomass every two weeks. Site Feedback, Efficacy of Herbicide Active Ingredients Against Aquatic Weeds, UF/IFAS Assessment of Nonnative Plants in Florida's Natural Areas, Florida Department of Agricultural and Consumer Services- Prohibited Aquatic Plant List, USDA Natural Resources Conservation Service- Plants Database, Identification and Biology of Nonnative Plants in Florida's Natural Areas, University of Florida Herbarium Digital Imaging Projects. It can grow in as little as 1% of full sunlight. Hydrilla is a submersed freshwater herb. Due to its competitive nature, Hydrilla has created monocultures, an area dominated by a singular species, rather than having a balance among many species, like in a normal ecosystem.

The UF/IFAS Assessment lists Hydrilla as prohibited. The plant’s appearance can vary considerably between regions, depending on the growing conditions. Use best practices to prevent introduction by cleaning boat trailers, propellors, diver gear and live bait wells. Individuals can be either monoecious (bearing both male and female flowers) or dioecious (bearing only male or female flowers). Extensive monospecific stands of Hydrilla can provide poor habitat for fish and other wildlife, although Hydrilla is eaten by waterfowl and is considered an important food source by some biologists. ACCLIMATION The most difficult stage of growing a carpet is at the start. Hydrilla can grow to the surface of waters as deep as 25ft and form dense mats and can still be found in all types of water bodies.

The dense mats of hydrilla decrease dissolved oxygen by inhibiting the water mixing areas, increase the water temperature by absorbing sunlight, create mosquito breeding areas, and negatively affect recreation such as swimming, fishing, and boating.
