Vegetable
Brassica oleracea
S tier
Brassica oleracea is the wild-cabbage species that humans sculpted into broccoli, cauliflower, kale, cabbage, kohlrabi, and Brussels sprouts—broccoli being the immature flower head form with tight green or purple buds on thick edible stems. Glucosinolates give the signature green-sulphur aroma when cells break; brief heat keeps florets vivid, long boiling dulls them. Within broccoli, heading Calabrese, sprouting types, and stem-focused crosses all sit under this species. Recipes calling for broccoli assume B. oleracea italica-group heads unless a specialty name is given. Use florets and peeled stems; leaves near the head are edible. Species-level identity links broccoli nutrition talk to its cabbage cousins.
