Discussion
Viola bicolor is the only pansy native to North America (V. B. Baird 1942; J. Clausen et al. 1964; A. E. Radford et al. 1968) and is the only annual Viola species that produces cleistogamous flowers (Baird; A. Gershoy 1934). Roots of V. bicolor have the odor of wintergreen when crushed (W. J. Hayden and J. Clough 1990).
