Myriophyllum spicatum, commonly known as Eurasian watermilfoil, is a submerged aquatic plant native to Europe, Asia, and North America. It features finely divided, feathery leaves that grow in whorls around the stem, giving it a bushy appearance. This plant can thrive in various freshwater habitats, including lakes, ponds, and rivers. Eurasian watermilfoil is known for its rapid growth and ability to form dense mats on the water's surface, which can hinder recreational activities and disrupt local ecosystems. It can outcompete native aquatic plants, leading to reduced biodiversity and altered habitats for fish and other wildlife.
