They are native to Europe, and B. salicifolium is in cultivation and has been introduced elsewhere. These are perennial herbs with alternately arranged leaves. The inflorescence is a solitary flower head atop the stem. The head has very narrow phyllaries, yellow ray florets and yellow disc florets. The fruit is a cypsela usually tipped with a pappus of scales; those growing from the ray florets may lack pappi.
