Fail Proof. Grows from South Florida to North Dakota without a hitch. Slow starter at seedling stage. Must keep the soil moist to wet and grow before temperatures reach 80 degrees. Stores up to 3 months under prooper rifridgeration.
Will take temperatures down to 30 degrees for short periods.

Have tried just about every Cos variety out there. I don't even bother trying the alternates anymore.

This variety is impractical as a spring crop where there are less than 60 days after the last hard frost before hot weather arrives. The best thing is to sow seeds in early fall. Thin plants to stand 8 to 12 inches apart.

If starting in fall, you can start seeds inside 2 to 3 weeks before the last frost free date, protecting them from hard frosts. Seeds will germinate better if they are planted in late summer and shaded to keep the soil cool and thus reduce evaporation.

To harvest lettuce, you can take the whole plant or snap off the outer leaves.
