Annual Fleabane is a summer annual weed that is common throughout most of North America. It is most common in the eastern and mid-western states. It grows to about 3 and 1/2 feet tall. The blooming period starts in early summer and continues through fall. It usually lulls during hot periods. It reproduces by seeds, which have white tufts and are carried by the wind. Annual Fleabane can sustain many soils from moist areas to dry areas, but prefers clay or gravel.
Leaves of annual fleabane are alternate. They are up to 4 inches long and as broad as 2 inches. The lower leaves are coarsely toothed and tend to be broader. The upper leaves are narrower and often have shorter or no stems. The upper leaves are not toothed but are hairy. The first leaves form a rosette.
