This is my opinion, but no matter when you start wsing as long as it reseeds in your area then it will be fine!! No matter if it is perennial, annual, veggie, or herb.

My guess- your weather will hit the 50s for just a few hours in the afternoon. The other 20 or so hours of the day will likely be pretty cold. WSing should be fine. If anything would sprout that fast, it would probably be a cold hardy plant that will tolerate cold just fine, like poppies.
