Viola odorata "Royal Robe"
(Pawla, USA, 1947)
Large, deep blue/purple and suitable for cutting. I've also noticed that it has the prettiest, heart-shaped foliage of any of the violets I grow and is less susceptible to red spider mites. It is lightly fragrant. This one seems not to send out runners but is, rather, clump forming. Quarts.
