CommentsAnother common name of Viola tricolor is Wild Pansy. Johnny Jump-Up is one of the parent species of the modern pansy, Viola × wittrockiana, which has larger flowers (1½" across or more). There are many cultivated forms of Johnny Jump-Up that have differently colored flowers of variable size. Some of these cultivars display characteristics that suggest hybridization with another introduced species, Viola bicolor (Field Pansy). In general, Johnny Jump-Up is a more robust plant with tricolored flowers, while Field Pansy has bicolored flowers that are smaller (about ½" across). This latter species also naturalizes in Illinois.
