Informational only: Vigorous grower with long roots that enable it to overwinter without heaving out of the ground. Outside skin is ivory-white, but the clove skin is dark red. Strong raw flavor, high sugar content, one of the very best for roasting. Extremely large size. Hardneck, 4-7 cloves per bulbs.

Grew 'German Extra-Hardy'. Strong, flavorful garlic with little aftertaste. This garlic did not upset the stomachs of people who normally get upset stomachs from garlic. The bulbs were small to medium sized, and the tops were very strong and large. Late-mid season.
