Calendula, Alyssum, Snapdragons, Annual poppies, godettia, sunflowers, portulacca and selene

sometimes Nicotiana, Nasturtium and petunias.

The thing with reseeding annuals is sometimes you end up with a whole lot of weeding and thinning out and sometimes they don't resemble the plants the seeds came from. If you plant an annual that's be hybridized your plant from dropped seeds can resemble any one of the ancestors of that hybrid plant or a mixture of them.If you start with an heirloom plant like calendula it will come true

Have you looked into the winter sowing forum? You can get some good info there

Thanks for the advice. I'll be sure to check out the forum later.

Different plants are more likely to reseed in one area than another. For me, Verbena boniarensis reseeds like crazy and so do annual rudbeckias. I also have snapdragons and calendula, as mentioned above. I second the recommendation to look into winter sowing. You can grow a huge variety of plants, including lots of perennials that you can enjoy for years to come, and very inexpensively. If you really want to get addicted, start collecting seeds and trading on the seed exchange forum. New plants for the price of postage and a little dirt. Happy gardening.

Many, many reseeds - larkspur, nicotiana. Some reseeds - portulaca, nasturtium, poppies, calendula, alyssum, snapdragon. For me, nicotiana usually reseeds to white, portulaca reseeds to white or yellow, larkspur to purple.

Alyssum, bacheler's buttons, johnny jump-ups, borage. Occasionally and sparsely, calundula, shirley poppy, and pansy. Verbena bon. reseeds, but comes up too late to enjoy. No nasturtium here, though I plant loads of it every year.

Dee, my Verbena boniarensis has been blooming for a few weeks already, and looks like it will be going until frost. Are you farther north? I guess mine is by the road, so the pavement holds heat and allows the seeds to germinate earlier.

I do have one spot, near the house, where the reseeders bloom in time to enjoy. The others are pretty small right now. Are you closer to the lake?

I'm in Grand Rapids, so not really by the lake.

I bought a few little market packs of Portulaca last year and planted them. I

was surprised to see at least a hundred tiny Portulaca seedlings coming up in the beds this spring. I just transplanted them once they got to about 2" wide by 3-4" tall. Now I have dozens of 10-12" wide by 6-8" tall Portulacas spread around the beds. Next year I should have a lot more! They are of every color, and they've been blooming about 2 months so far. They do pretty well in dry summer conditions. They produce these tiny seed pods directly under the finished flowers, and within those pods you find dozens of tiny, dry, dark gray seeds that look similar to poppy seeds or black powder. You can collect them too.

I've had good results with Celosia as well. I like the burgundy leafed ones with red tassels. I grow zinnias here in De with no luck from seeds coming up the next year.

docmom, I'm in Ada. I use a ton of Verbena b. I get small flats of it at Bos and scatter it through one bed. It comes into it's own .late summer. I got a flat of larger plants in the spring at Koetsiers and put it in the annual bed near my front door. It's been awesome since early July. Most of my re-seeded Verbena b. is just a few inches tall, but the one in a little corner near the foundation and the concrete steps has been full and tall for a few weeks. Verbena b. is deer proof, drought tolerant, and uncommon. Love the stuff. You can see some of it in my instagram feed: https://instagram.com/deeinmi/
