This is an extremely winter-hardy butterhead with pleasant, mild, velvety leaves. It is excellent for salads anytime, but especially exciting to have something green and crunchy while snow is still on the ground. Last year, starting on the first day of spring, we sold this variety to Johnny Brenda's kitchen in Philadelphia while they waited for their regular farmers' early lettuce crops to mature. It's a Pennsylvania Dutch selection of the now-extinct late 1700s variety known as White Tennisball. Roughwood Seed Collection acquired this seed in 1994 from renowned Lettuce seed collector Mary Schultz of Monroe, Washington.
