Najas minor
Also called Slender Naiad, Brittle Naiad, Brittle Water Nymph, European Naiad, Brittle Leaved Naiad, Eutrophic Water Nymph, Slender Leaf Naiad
Brittle waternymph (Najas minor) is a fast-growing annual aquatic plant that lives fully submerged in calm, nutrient-rich water. It is a weedy invasive in parts of North America, so it is best kept out of the garden pond unless you can contain it.
Najas minor, known as brittle naiad or brittle waternymph, is an annual aquatic plant, a submersed herb. It is native to Europe, Asia and North Africa from the Netherlands to Morocco east to Japan and the Philippines, including China, Siberia, Central Asia, Iran, Turkey, Ukraine, Germany, France Italy and a host of other countries. It is now introduced to North America and considered a weedy invasive species in the eastern half of the United States from Florida to Oklahoma to New Hampshire to Ontario to South Dakota. This plant prefers calm waters, such as ponds, reservoirs, and lakes, and is capable of growing in depths up to 4 meters.
Najas minor is distributed widely in the Northern Hemisphere, such as Canada, the United States, Japan, China, Europe. This species is also reported from tropical Asia (Thailand), but the report is now recognized as an identification error.
