Pilosella albiflora (synonym Hieracium albiflorum) is a common and widespread North American plant in the sunflower family, known by the names white hawkweed and white-flowered hawkweed. Pilosella albiflora is found in forests and woodlands at low to moderate elevation. It is similar its relative the common dandelion, except for having more than one flower head per plant, sometimes 50 or more in a flat-topped array. Each head has 6-25 white (rather than yellow as in most related species) ray flowers but no disc flowers.
Invasive in North America.
