Epilobium ciliatum
is a species of willowherb known by the common names Fringed Willowherb and American Willowherb. This plant is found in many parts of the world. It is native to much of North America and eastern Asia, and it is an introduced species in much of Eurasia and Australia. It may be found in a great variety of habitats, including disturbed areas and roadsides. This is a clumping perennial often exceeding one and a half meters in height. It has thickly veined lance-shaped leaves which may be up to 15 centimeters long toward the base of the plant. The foliage, stem, and flower cluster are covered in bristly hairs and glands. The trumpet-shaped flowers have four petals which are so deeply notched they look like four pairs. They are white to light purple or pink with dark veining. The fruit is a narrow, hairy capsule up to 10 centimeters in length, and it may be held on a long stalk.
