@Ashley I have a few potted ones, and a load of seeds that I was going to mix together and spread too. I’ll do similar to you as I have clay and very chalky soil. I was thinking maybe raising it a little to add some soil to help?
I'm also adding flowers to my garden this year. I have my vegetable garden then next to it I'm going to plant a pollinator garden for the bees and butterflies. I dug out a garden bed and added leaves and kitchen scrapes through the fall and winter to help my soil( I have clay soil). In a couple of weeks I'll spread some monarch rescue mix, marigolds, butterfly flower, columbine, butterfly weed, sunflowers, and a few herbs seeds. It'll be a bit of a chaotic garden(since I'm going to just spread the seeds) but the flowers should be beautiful.
