Time of bloom: May to August.
Seed-time: June to September.
Range: Throughout North America except the far North. Habitat: Alluvial soil; fields, meadows, and thickets.
Often spoken of as the "common" Fleabane, but not usually an abundant weed, for it has decided preferences, growing only on moist ground and liking partial shade.
Stems one to three feet high, single or in tufts of two or three, slender, leafy, softly hairy. Lower leaves spatulate to long-obo-vate, obtuse, coarsely toothed, narrowing to short-margined petioles; stem-leaves more narrow and pointed, often entire, clasping by a heart-shaped base. Heads in a corymbose terminal cluster, each nearly an inch broad, with greenish yellow disks and innumerable thin, fringy rays, pale pink or pinkish purple, sometimes nearly white. Achenes hairy, with pappus of one funnel-formed row of fine hair. These seeds are a common impurity of grass and clover seeds, though, being small and light, they should be readily removed.

Controlled by drainage and cultivation of the ground.
