Select your Product Preference

Review the weed description, then select from the control options below.

Hydrilla (Hydrilla verticillata) is a perennial plant that forms dense colonies and can grow to the surface in water over 20 feet deep.  Hydrilla branches profusely.  It can extend across the surface forming thick mats. Hydrilla can reproduce by fragmentation, from seeds, from turions (axilary buds), and from tubers. Leaves are blade-like about 1/8 inch and 3/8 inch long with small tooth margins and spines on the underside of the midrib which make them feel rough when drawn through your hand from base to tip. Leaves are usually 4 to 8 in a whorl.

Hydrilla is native to Europe and Asia and was probably brought to the U.S. for the aquarium industry. It is considered a noxious pest because it grows so rapidly, out competing and eliminating native species, and forming surface mats that hinder recreation, navigation, and water intakes.

Hydrilla is often confused with the native Elodea.
