I agree with both responders above. Also, rudbeckia annual varieties reseed vigorously. The rudbeckia, snapdragons, calendula and verbena all have normally been annuals, but the past winter was so mild that many of those plants survived and were up and blooming early this season. I also second the wintersowing recomendation. I've been doing it for years and it's an addiction in itself. And it's fun to collect seeds and trade with other gardeners, too. Good luck! Martha

Hi Karen, I have some pink poppies that I can trade and some no ID pink Cleome and Cleome "Rose Queen" which is rosey pink - both of which are self-seeding. I think I might have some others too, but I can check. I'll send you an email. Sue

Hello Greenthumb - All of the varieties of annuals you have listed have self - sowed for me, It doesn't really matter what variety - they all will self sow, The Balsam tends to produce single flowers after several seasons of self sowing, and snaps will become less showy than their parents. I have a hillside that is covered with blue batchelor's buttons that have resown themselves for more than 10 years. There is Portulaca - moss rose that grows and flowers here beautifully in the gravel between patio stones that seeded themselves there from the garden. Bells of Ireland is at its best when it self sows. You have to give these self sowing annuals real good to ideal conditions (well drained fertile soil, little competition with weeds) and a full day of sun for them to return from self sown seeds. Good luck!

I know that some seeds need light to germinate altho I couldn't off-hand tell you which ones so I'm posting a link which gives some info. Not all on the list are annuals. I expect that if the seeds fall naturally on a thin mulch there may be enough light for germination anyhow. I don't use a lot of annuals but do love those self-seeders whether annual or perennial. They are worth a lot in plant value altho I really need to replan my garden because I tend to let them take over. Here is a link that might be useful: flower seeds that need light to germinate
