Cold *moist* storage is what's needed  for breaking dormancy in seeds
requiring stratification.  And the time is usually on the order of
10 weeks or so.  However, Viola tricolor (johnny jump ups) just need
soil temps of 70oF to germinate quite well... no  stratification required.

When did you clear the area, and how did you do it?  Both of these
have roots to kingdom come, and delight in popping back up when you
think it's safe to plant.  If you just mechanically cleared the area
last year, I'd tend to encourage you to leave the area bare this
year so you can spot the new growth and nab it before it gets very far.
