The bread seed poppies grew and flowered. They were a double pink. I cut down the stalks and didn't let them go to seed because I thought the dry stalks detracted from the plants the first year. I also had some California poppies the first year that were nice and their foliage stayed nice looking longer. The second year I didn't plant any poppies and the bed is so full of plants now that I don't think seedling poppies could compete.
