Lettuce, Florence (Organic)
Lactuca sativa. Green Oak Leaf. 30 days baby; 55 full.
Bright green oak leaf lettuce has the crisp texture of a romaine. The surprising sweet crunch made us think about dividing the oak leaf lettuce category into butter oaks and crisp oaks, but that is another conversation. The dense heads resist bolting in the field, instead they just keep getting bigger. A fabulous lettuce for full heads, cut-and-come-again or salad mixes. We are always surprised at how many great and unique lettuces are out there; Florence was the most impressive of our USDA GRIN accessions grown back in 2013.
Seed produced by Avoca in Corvallis, Oregon.
Sow indoors in flats with good potting soil year-round. Transplant into the garden 3-4 weeks after sprouting at 3″ spacing for leaf, 12″ for heads. Alternatively, direct sow March through September. In our area, lettuce can go through winter if protected. Succession sow for continual harvest.
Collect seeds when flowers are downy like dandelions. Cut seed heads and place upside down in a bag to dry for a few days. Knock seed heads against side of bucket or tote, rub downy fluff off seeds. Winnow and screen to clean.
