I've been wintersowing for 10 years, and honestly, it depends on the year. Most of those years I wintersowed my tomatoes but 2 years ago it was so cold they didn't sprout until early May, right after I gave up and bought plants. So the next year, I started them inside under lights...
Don't get me wrong, I love wintersowing, but it really is a leap of faith and results could vary from year to year in a temperate climate. I think it a relatively cold climate, like mine even, it works great for perennials. It usually works well for annuals, but in a cold spring, results can be disappointing.
