The cutest little lettuce you ever did see! “Tom Thumb” is an heirloom miniature Bibb lettuce that dates back to the 1830’s. Delicate flavor adds to the charm of this variety. Its crumpled, pale heads about 4-5” across make a perfect salad for one and are surprisingly hardy in summer heat. 50 seeds/2.00. 1/2 oz./9.00, 1 oz./15.00.
