- DogwoodGalVerified ReviewerRated 5 out of 5 stars3/28/26Great 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.

- Patti O.Verified BuyerRated 5 out of 5 stars3/2/26Red Sails leaf lettuce is an impressive grower
I am in Zone 9b and direct sowed red sails in early Feb. I will pick for my first salad this week. It had nearly 100% sprout and has grown quickly. It is strongly outperforming Giant Caesar romaine which was similarly planted. I will buy this again next year.

From raised beds to containers to crummy hillside soil, this variety has produced time after time. We've had a mild winter (no snow), and I still have heads growing in raised beds under frost cloth. It tastes great and lasts well in the fridge.
