Milkweed. The flower heads can be fried in batter. flower buds first appear in early summer and can be harvested for about 7 weeks. They look like immature heads of broccoli. Milkweed pods are delicious in stew or just served as a boiled vegetable, perhaps with cheese but be sure you eat only immature pods. Boiled young shoots, unopened flower buds, flowers, and young pods are said to taste as good as asparagus and other cooked greens. The only the young shoot (under 15 cm) should be eaten.
