|'Brauner Trotzkopf', also known as 'Hardhead' or 'Weber's Brown Head' lettuce, is an heirloom variety. This is a small plant, measuring generally 6-7 inches across, and is a butterhead type. The leaves have green-white edges, and are crumpled and mottled with dark brown which darkens to dark purple toward the centers. This is a winter variety which thrives in cold frames. Slow to bolt. Start from seed 4 to 6 weeks before average last frost date. Sow seeds 1/4 inch deep in wide rows and thin to 8 to 12 inches apart. Thinned seedlings can be replanted. Keep soil moist but not soggy. Protect from rabbits and slugs. Extend the harvest season by planting successive crops. Summer heat causes lettuce to bolt. Pick outer leaves as they grow or harvest all at once. Harvesting when weather or day temperature is cooler will result in crisper leaves. Do not harvest lettuces until you are ready to use it.
