Summertime Lettuce (68 Days)
Bred by Dr. Baggett at Oregon State, the objective of the Summertime Lettuce was to develop a head lettuce that would mature in summer’s heat without bolting and was also resistant to tip-burn and rib discoloration. The Summertime Lettuce consistently yields the highest percentage of usable heads in trials. The flavor is good & the texture is very crisp.

Tips: Summertime Lettuce needs fertile soil for optimum growth. Work in compost or well-rotted manure into your soil before planting. Provide adequate, even moisture for the best growth. Mulching helps retain moisture.
