A few things you and others should know. If a person is allergic they will have gas for about a day but it will pass. Also some women will have an aftertaste of onions, this has not been reported by males only by women and nobody knows why. Not only are the flowers edible but the pods are used in a few Asian dishes. I like the flowers and nibble on them from time to time and like you think the taste like a sweet lettuce.
