Bought a violet from Lamb's nursery in PNW years ago. It is small, parchment colored with an apricot heart. Have lost contact with nursery and name of plant. My question is not so much about it's identity as to why is does not thrive and spread. The purple wander about and are almost weeds. The white do well enough to satisfy me. Freckles borders on being a pest. Good thing it looks so great. Do some violets need lime in the soil. My soil is sandy, moist, shady and acid.
