In the nomencla- ture of this list, the monograph of Gray has been fol- lowed (Gray's Syn. Flora, vol. 1, pp. 195-'20i). Violets are easy to grow, particularly if an effort is made to imitate the conditions under which they natur- ally occur. Some of them are woods species, others swamp species, and others inhabit dry plains. They are propagated readily by means of division and in some species by runners. Sometimes seeds are used, but not commonly. Many species that grow mostly to single stems in the wild make large full clumps when given good opportunity in the garden. Fig. A. Plant perennial. B.
