IdentificationCommon Sneezeweed is a handsome plant, with its broad inflorescence of bright yellow rays (toothed at the tips) and yellow, dome-shaped disk. Stems grow 2-4 feet tall, with many elliptical leaves that lack stalks but which are decurrent on the stem (each leaf base extends as a narrow "wing" down the stem). The rays are short compared to sunflower species (Helianthus).
