Brown knapweed is a perennial plant that grows 1-3 ft (0.3-0.9 m) tall and invades dry fields, roadsides and meadows. The basal leaves are oblanceolate to elliptic and 2-10 in. (5 -25 cm) long. Leaves become smaller and more linear as they move up the stem. Flowering occurs from June to September, when magenta flowers appear in 1-1 1/4 in. (2.5-3.2 cm) wide, solitary heads at the tips of the branches. Brown knapweed is native to Europe. |
