I bought a package of organic edible flowers today to dress up a potluck dish and have lots of flowers leftover. I found the "edible flower list" from Julia Crab that someone posted but there are a couple flowers in my mix that I'm not sure whether they are safe or unsafe. I have snapdragon, marigold, johnny-jump-ups and cornflower/bachelor's buttons. Johnny-jump-ups appear to be ok, but what about the rest? Any idea? Thanks!
