Ah, I just realized there was a violets form -- great!! I originally posted this in perennials.I have an area, maybe 100 sq feet, under a pin oak that I would like to cover with violas of different types. It goes from all dappled shade to a couple of hours of sunlight. Right now the soil is clay with a crummy weed/grass covering. I don't want to dig too deeply and disturb the pin oak's roots. Can I just dig about 6 inches and add lots of peat moss for moisture? Will that do for viola odorata or cornuta Purple Showers or Maggie Mott?

Also, starting odorata from seed, does it need to be in the frig or in the freezer. And, if freezing, for how long?
