Variety walteri shows an interesting transition between caulescent and acaulescent violets; its growth habit is similar to Viola odorata (A. E. Radford et al. 1968). D. Klaber (1976) reported that V. walteri forms mats to 0.6 m in diameter.
Viola walteri and V. sempervirens have a similar growth habit, the abaxial and adaxial leaf surfaces of their mature leaves are often distinctly purple-dotted, and their stems persist through the winter.
Variety walteri is reported to hybridize with V. striata (= V. ×cooperrideri H. E. Ballard).
