- CharityVerified ReviewerRated 5 out of 5 stars6/28/26The best lettuce ever!
This variety of lettuce has to be my absolute favorite! I planted this lettuce back in early spring and it’s still going strong in late June. I’ve never had a variety hold up this well in heat( I’m in growing zone 6b-7a) and not turn bitter or bolt. I also love the color and shape of the Red Sail’s lettuce heads. This will be my go to lettuce from now on.
