(B. oleracea) Old World cabbage relatives that are grown for succulent flower heads or buds. Needs rich soil, abundant moisture, and cool weather. Best grown as a fall crop, except where summers are very cool. When the plants reach full size, they send up a central stalk, which yields the “sprouts.” These are harvested whenever they have reached a good size, but before they begin to split or open. A mild frost at this stage improves the flavor, making a sweeter “sprout.”
100 days. The standard open-pollinated variety since the 1890’s.
