Marathon Broccoli (Brassica oleracea) is a highly productive, cold hardy broccoli that is farmers and small scale growers rely upon for fall and spring crop production. Large, uniform central heads form on low lying plants (approximately 2 feet tall), that once harvested give way to further uniform side shoots, larger than a sprouting broccoli. This one really goes the distance.

Broccoli is a biennial crop that can be spring or fall sown. Plants will produce harvestable flowering heads approximately 90-100 days when seeded in ideal soil and climate conditions.
