          White Avens and Yellow Avens
          Geum canadense and G. aleppicum
          These weedy native wildflowers like to grow in dappled shade or woodland 
          edges. The flowers are borne on two-foot tall stalks. Each seed on the 
          seedhead (shown in right-hand photo) is tipped by a tiny hook that can 
          catch on animal fur or human clothing for transport to a new location.
