Crispino Iceberg or Crisphead Lettuce - Organic

seeds
Lactuca sativa
(60-65 days) Open pollinated.

Lettuce master Frank Morton said, “Ozzie and Harriet salad of my youth is making a comeback, and this is the backbone for it.” This old-school iceberg gets right to business making 6–7" light green icy heads with nearly white hearts. The lightly toothed and wavy leaves wrap early on a big vigorous 15–20" diameter plant, delivering a classic medium-crisp kick paired with tender juicy refreshment. In our hot humid 2018 lettuce trial, Crispino was uniform and blemish-free, holding well without tip burn.

Additional Information

Iceberg or Crisphead

According to Vaughan’s 1904 seed catalog, Iceberg takes its name from the small indentations in the leaf that fill with dewdrops giving them a crystalline appearance. With its toothed and fringed light green leaf, famous crunchy juicy texture and mild sweet flavor Iceberg has become an iconic American food. Late to make mature heads, Icebergs face heat and stress with grace and tolerance—lettuce lessons for our politicians?

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.
