Some popular edible flowers include nasturtiums, pansies, snapdragons, flowering maple, bachelor's buttons, dianthus, scented geraniums, chrysanthemum daisies, margarita daisies, marigolds, and calendulas.
Eat only the petals of edible flowers, and always remove any trace of the pistils and stamen. So your digestive system has a chance to get used to it, introduce flowers into your diet one at a time, in small quantities. And always be sure you like the taste of a flower before adding it to a recipe.
Remember, just because a flower is served with food, it is not necessarily edible.
