I TOL' you I had a lot of seedlings! And this isn't all of them. I just kind of go nuts about sowing seeds.
I think these are snapdragons, with one tray of calendulas. I put them in trays because I have too much work in some the flowerbeds to be sowing a lot of seeds there. I will over seed these, when I put the transplants in the ground. It is a good technique, works most of the time.
