A favorite to use as baby greens, 'Red Sails' is ready to harvest after just 2 or 3 weeks and grows to a full head in just over 6 weeks. Very heat tolerant, the soft buttery leaves will grow well into warm weather without getting bitter. Contains more vitamins A and C than grocery-store lettuce! Attractive container variety, too. An All-America selections winner.
