Well, since Farmerdill says anything will work, I recommend Acadia. I found it 3 years ago and was enchanged. It makes smaller heads, but very prolific (multiples at one time) and great for re-growth. This means I can easily pick the amount of broccoli I want for whatever reason. And it tastes delicious.
If you want an OP, Green Goliath is the best that I have tried. Early enough for spring planting here, staggered harvest, good side shoots. Only two varieties that I have tried that were unsatisfactory were Gypsy and Belstar, not suited to my growing conditions.
Thank all of you for your input regarding my broccoli question. I've decided to go with Green Magic and Gypsy in the Spring and Arcadia in the Fall. I have lots of space in my garden so can afford to experiment.
