I eat broccoli and cauliflower. There are some bok choy-type vegetables at the market that have flowers and you can eat mustard flowers. You can sometimes find baggies with nasturtiums, pansies, calendula or other flowers at the store. Sometimes you can find candied violets. Of actual bouquet flowers, my pet parrot that I used to bring to work (I worked at a flower shop) loved to eat roses and carnations. I tasted the carnations and they taste like pepper. I wouldn't eat such flowers, however, because they spray them pretty heavily since nobody's going to eat them.
