What seeds do you no longer have? Some here might be able to spare a few and have them to you in a few days. In your zone you really have until early April, at least, to start tomato seeds. I am just starting mine now and will start more in the next couple of days. They say 6-8 weeks from last frost dates. If you go as late as recommended, 6 weeks before your last frost date, is April 1. You are not even late until after that, and you could still start seeds after that you might just have a crop a few days or a week later. If you can get a few plants locally, you can still get them in plenty early and mix them with the ones you wanted planted just a few days or a week later.
