Time of bloom: July to November.
Seed-lime: September; the later ripened burs persistent on the stalks all winter. Range: Throughout North America. Habitat: Fence rows, roadsides, waste places.
Smaller than the preceding species, the stems being three to five feet in height, erect, grooved, and branching. Leaves broadly ovate, obtuse, usually heart-shaped at base, light green and woolly-hairy beneath, darker and smooth above, the stout petioles hollow, and not grooved as are those of Great Burdock. Heads numerous, racemose on the branches, sessile or on short peduncles, about a half-inch broad; bracts of the involucre short, smooth or slightly woolly, the hooked tips, like those of Great Burdock, turned inward, the outer rows somewhat spreading, the inner ones erect and shorter than the flowers. Achenes show almost none of the gray and brown mottling characteristic of those of the larger weed. Cows are fond of the plant, but if it is eaten by them in any quantity, the milk takes a bitter flavor.
Means of control the same as for Great Burdock.
