Might well be Calendula, a flowering annual plant. If you don't get a for-sure ID here fairly quickly, the folks on the Name That Plant forum are whizzes at IDing plants.

(You also have a large weed on the left side, lamb's quarters, AKA Chenopodium album or other Chenopodium species. You want to remove that since it appears to be out-competing the flowering plant.)

Thanks fir the reply, nhbabs

These plants cam from a Wild Flower Seed Pack I bought at the store. Listed on the pkg is "Calendula Officinalis" so it is probably that.

The other plant, you say is a weed? Research says it is highly edible.

Should the Calendla Offinalis spent flower heads be pruned back to encourage more growth?

Yes, removing spent flowers, called dead-heading, does help plants produce more blooms.

I guess you're right about the lambs quarters ID, NHBabs, although LQ foliage is sort of dusty looking, and this seems a bit bright - maybe that's just the contrast with the calendula foliage, which is a little yellowish.

I agree with calendula identification. There are different varieties and that looks like a nice color combination. The flower is edible but I never eat mine. You might deadhead to encourage more blooms but calendulas readily self sow for me here in NH. This spring I transplanted some to other parts of the vegetable garden and pulled out some. So if you want some next year, let it go to seed at the end of the season.
