A heirloom, cool-season variety known for producing large, round, blue-green heads that average 7 to 10 inches in diameter and weigh 5 to 7 pounds. These vigorous plants are reliable, bolt and split resistant, and are prized for their ability to store well into the winter. The resulting cabbage is a versatile, all-purpose vegetable that can be eaten fresh in salads or cooked, and is excellent for sauerkraut.
