Broccoli is very hardy. Fall broccoli should be started a month and a half before the last hard frost, and then planted out. All broccolis like moist, fertile soil and cool weather. Protect the heads from most rain, that excess moisture causes rot and mold; row covers or a cold frame work well for getting an early start.
Very high in antioxidants.
