Discussion

Viola riviniana has become established in several states on the Pacific Coast. It is cultivated and sold through nurseries in the United States. In the nursery trade in California and elsewhere, it is incorrectly referred to incorrectly as V. labradorica ‘Purpurea.’ In some plants shoots arise from adventitious buds on the roots (A. R. Clapham et al. 1987; T. Marcussen and T. Karlsson 2010).
