Tom Thumb Butterhead Lettuce

seeds

Lactuca sativa
(46 days) Open pollinated. This venerable and adored miniature butterhead was introduced in England by H. Wheeler & Sons in 1858. It came to the States ten years later. One customer wrote to Burpee’s in 1894, “It is just what the gardener wants…a good dwarf variety, a quick grower.” Former Fedco staffer Heron called it “fairy cabbage.” In the dewy cool of spring or fall, Tom Thumb forms its extra-early tightly bunched tiny head. With sweet buttery light-medium green outer leaves and creamy white crunchy centers, it’s tasty and attractive for early markets. Can be closely spaced as the heads seldom exceed 5" in diameter. Please do not attempt to grow it in warm temps—it turns into an ugly toad!

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.
