Two primary color forms exist, Viola pedata var. lineariloba ("concolor"), which is a solid pink-lilac-lavendar color, and var. pedata ("bicolor"), in which the superior petals are a deep red-purple and the lateral and interior petals are similar to the concolor variety. Less common is Viola pedata var. linearloba forma alba, which is a white flowered form.
Birdsfoot violet favors well drained, acidic soils in full to partial sun environments. It is difficult to cultivate in typical garden environments because it does not tolerate rich, organic garden soils and excess moisture.
