I am winter sowing my snaps this year. I did start a batch in spring. However, the weather here slowed everything down to a crawl. We had three straight months of rain. Hard to germinate in those conditions. Then it went from rain to 90 degree weather. Seeds had germinated but little growth. It took some time but by August, those babies were blooming and I had more than I needed. I do suggest the winter sowing method. Plants are stronger and healthier when sown this way and the wait is not near so bad.
