@lalambchop1 Leslie, I agree with what's written by others. I tried winter sowing three winters ago with mixed results. My major difference, with most other places is that I don't have any standing snow for too long. Perhaps three days at the most. I somehow feel that w.s is particularly suited for the heavy winter type of climates. Instead I do something similar but much later in the season I sow my pots about 8 weeks before the warming up of spring.I'm doing that just now with many of the N.American wildflowers such as Penstemons, Buckwheats, Lewisias etc. I sow my seeds in individual pots (4" wide) and cover them with Saran wrap and leave them under a cold shady place (I've a got a large Arizona cypress for that) until the stratification period needed is met. I have started earlier with other species that need longer cold periods: Erythroniums. These have a layer of fine gravel on top instead. Also I'm expecting that some of my pots might spend more than one year until they sprout. So I keep a seeding pot ghetto in just a corner of my work area and keep an eye to await any news. I keep hearing of others that get surprises even 4 years after!
