Lactuca sativa
(52 days) Open pollinated.

This dark green uniform Nancy-type butterhead caught lettuce master Frank Morton’s eye with its large plant and head size, and workhorse performance. We were equally wowed as slow-bolting Optima held its lush looks and high quality in 2018’s hot and steamy lettuce trial. It continues to perform consistently well for us in heat and stress. Optima’s juicy sweetness and silky texture could truly define a new category: Tenderheads! Released by French seedhouse and breeder Vilmorin in 1995. High resistance to DM, BR, and TB.

Additional Information

Lettuce

  • 700–1100 seeds/g.
  • Days to maturity are from emergence after direct sowing; for transplants, subtract 20 days.

Culture: Direct seed outdoors as soon as ground can be worked and repeat every 2 weeks for continuous supply. Or start indoors in March and at regular intervals thereafter for early transplanted successions. Optimal germination temperature range 40–70° though many varieties won’t germinate in soil temps above 75° and most shut down above 80°. Thin sowings frequently and ruthlessly to a final distance of 1' for full heads. Heavy nitrogen feeders.

Hardy. All save icebergs tolerate heavy frost. Fall and overwintered harvests are becoming standard practice. For summer harvest, select varieties carefully: bolting, bottom rot and tipburn are problems if a variety can’t take the heat! Using shade cloth can keep lettuce tender and sweet longer into summer. Sesquiterpene lactones produced in the latex render lettuce bitter when it bolts.

Saving Seed: Saving lettuce seed is easy! Leave spring-planted lettuce heads to bolt. Flowers will become white tufted seeds. Once dry on stalk, rub seeds off the plant into a paper bag. To ensure true-to-type seed, separate lettuce varieties by 10 feet.

  • BOR: Bottom Rot
  • DM: Downy Mildew
  • LMV: Lettuce Mosaic Virus

Cultural controls: rotation, reduce duration of leaf wetness, plant parallel to prevailing winds, use wide spacing, control weeds, use well-drained fields in spring and fall.
Material controls: MilStop
