The bright yellow broccoli flowers are edible and delicious. If you miss harvesting at the tight bud stage, you can still harvest broccoli, even with the flowers open. Broccoli flowers can be eaten raw or cooked. Use them as an edible garnish or include them as a nutritious and attractive addition to any salad. Completely opened flowers will wilt when steamed, but partially opened buds retain their shape. Broccoli flowers have a pleasant, mild flavor.
