I know marigolds almost always work to reseed this way, and poppies: but I had almost no luck with Zinnias or a collection of other annuals over the years.. trying Nasturtiums, Echinacea , and different kinds of daisies this year in multiple colors as well as different varieties.
I'd love recommendations. I tried bleeding heart seeds earlier this year & not a single one grew.
So- I'm looking for recommendations, as I'm hoping to have a wide-variety to plant in the spring.
