Better Devil Romaine Lettuce - Organic

×
seeds
Lactuca sativa
(60 days) Open pollinated. A really superior romaine lettuce from breeder Frank Morton. When it romaines, it sends up gorgeous purple ruffled center flag leaves. Its large veins, green tinged with purple, are crunchy, juicy and sweet with a hint of bitterness. The texture of its tapered cos-like leaves is chewy and pleasant. Recommended for early spring planting; resisted BOR and showed a moderate ability to withstand heat. Plants compact, uniform and dazzling even when crowded. OSSI. Breeder Royalties.

Additional Information

Romaine

Also called Cos. Large crisp-stemmed leaves wrap into a tall head with buttery but snapping blanched centers. Great performance in cold and heat.

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.
