Perfumeballs or Rayless Gaillardia is a slender, upright, clumped perennial, to about 30 in. tall, often forming dense stands. Fragrant, solitary flowers are terminal on leafless stalks. Rays are few, yellow to orange or red, very short, and soon falling off. Reddish-brown disc flowers are numerous, forming a rounded, pincushion-like head. Leaves are all basal.Not as showy as G. pulchella, but what it lacks in color is made up in fragrance. Adequate moisture and removal of mature flower heads will encourage flowering until fall.
