2001 - Plans are now being made for treatment to begin this summer. ANPC will issue notification of treatment dates and places through local newsletters and on this web site as well as their own. The Council s meetings are always advertised in local newspapers and will be posted on this web site. Leaves occur in whorls of three to six, closely spaced along the stem. The edge of the leaf has visible spines, making it feel rough.
Hydrilla produces small, white flowers at the water s surface in the summer.
The plant is native to central Africa and possibly Australia but now is found in temperate and tropical regions around the world and apparently entered the United States as an aquarium plant and was sold to retail aquarium dealers across the country. The plant has now spread from Florida, where it was first found, across the southern United States as far north as Washington, D.C. to Texas, Arizona and California. Hydrilla mats interfere with fishing, boating, swimming and water intakes. They displace beneficial aquatic plants and create breeding places for pests. The plant is difficult to control.
