Crisp Mint Lettuce (60 Days)

The search for lettuce that tolerates the hot months of summer could be over for you. We have always loved Jericho but the Crisp Mint Lettuce has proven to be a worthy rival. The ruffled mint-colored leaves are crisp and sweet even in elevated temperatures. Young heads are rather open but tighten up as they mature, growing to a sturdy 10”. Harvest mini or full-sized. Experiment by growing this as cut-and-come-again lettuce, (we discovered this is possible thanks to our resident groundhog).

300 seeds
