Viola tricolor. These perky little flowers are old-fashioned heirloom favourites and look like miniature pansies with lavender, yellow, and white faces. Direct seed Johnny Jump Up viola seeds from April to July. Sow seeds 0.6cm (0.25″) deep, and they should germinate in 12-14 days. Johnny Jump Up viola seeds self sow fairly readily, but they do not take over, and can be easily raked under if unwanted. These look rather good in containers, and their flowers are edible. If you want to try your hand at making candied violets, Johnny Jump Ups are the place to start. Or simply pick some of the fresh flowers and scatter them over salads and summer meals.
