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.

Red Sails is a vigorous and very easy to grow lettuce. I place them here and there around the greenhouse in any vacant spot I have available.
Highly recommend.

- DogwoodGalVerified ReviewerRated 5 out of 5 starsMar 28, 2026Great surprise
I went to prep my neglected beds for spring planting and there was a full row of beautiful large red green leafed lettuce. Very impressed and will plant again. 8A in a raised bed and only natural water after first few weeks. It was under frost cover cloth.
