plant id question
I have this perennial ground cover in my garden and I would like to know what the plant is and more about it. It is a shade loving plant, happy among ferns and moss. I thought it might be a wild violet, Viola howellii, but the flower seems different. The leaves are heart shaped, with toothed edges, 3/4"-1 1/2" wide. The blooms, held above the leaves, occur spring through early summer. It has a tough root system, and is a moderately spreader, also somewhat tolerant of dry soils. Thanks.
