Eurasian watermilfoil
About This Species
Eurasian watermilfoil is an aquatic plant which has been let loose from aquariums. It prefers still or slow-moving water with silty or sandy bottoms. It spreads by roots, seeds, buds, and stem fragments. Eurasian watermilfoil can quickly take over waterways, causing sluggish water that attracts mosquitos and reduces the recreational potential of the waterway such as swimming and boating.
How to Identify
Eurasian watermilfoil has reddish-brown stems with very thin, feathery green-black leaves. Flowers are small, red or yellow, and stick out from the water 5 – 10 cm. Fruits are small capsules.
