Tom Thumb Lettuce
Butterhead Lettuce
Tom Thumb Lettuce is a diminutive butterhead variety that packs serious charm into a frame no bigger than a baseball. This early 19th-century American heirloom matures in just 50-55 days, making it one of the quickest lettuces you can grow. Hardy across zones 2-10 and standing only 4-6 inches tall, it slots perfectly into small spaces, containers, and succession plantings where you want frequent, steady harvests without waiting two months. The leaves are bright green with a buttery, smooth texture that makes for stunning whole-leaf salads.

Highlights
Tom Thumb's real appeal is its miniature stature combined with heirloom reliability. These small heads reach full size in just over six weeks, yet deliver the tender, buttery leaves of a proper butterhead lettuce. You can succession-plant every two weeks for a continuous supply, or grow it in tight spacing where standard lettuces would struggle. The bright green leaves and compact, tennis-ball-sized heads make it as beautiful on the plate as it is quick to the table.
Common Uses
Harvest whole heads for dramatic, tender salads where the compact size becomes an elegant presentation. The bright green leaves and smooth texture shine when piled whole with coarsely chopped vegetables. You can also harvest individual outer leaves throughout the plant's life, allowing the inner leaves to continue growing for extended picking. The quick maturity makes it ideal for succession planting to ensure a steady supply of fresh, buttery lettuce from spring through fall.

Care Instructions
Start Indoors
Start seeds indoors 4-6 weeks before your anticipated transplant date. Maintain soil temperature between 60-70°F for reliable germination.
Transplant Outdoors
Transplant seedlings outdoors when soil becomes workable in spring. Space plants 8 inches apart, with 8 inches between rows. Harden off seedlings before moving them to the garden.
Direct Sow
Direct sow outdoors as soon as soil becomes workable in spring. Continue sowing every 2-3 weeks until 6 weeks before your first fall frost for successive harvests. Sow seeds at a rate of 12 per foot, then thin to 6 inches apart. Using row cover can improve germination and prevent soil crusting.
Harvesting
Full-sized heads are ready to harvest in 50-55 days from direct seeding. Harvest when heads reach about the size of a large apple or tennis ball. You can remove the entire plant by cutting it about 1 inch above the soil, or extend your harvest by picking individual outer leaves and allowing the inner leaves to continue growing. Check daily for leaves ready to harvest, as lettuce eventually becomes bitter as it begins to bolt. All heads will eventually bolt in warm weather, so harvest promptly once mature.

History & Origin
“Tom Thumb Lettuce honors the famous P.T. Barnum performer General Tom Thumb, a household name in early 19th-century America. Named as a playful reference to the diminutive showman, this butterhead variety emerged during an era when American gardeners were developing regional heirloom varieties suited to their climates and available space. It has remained continuously cultivated and seed-saved for nearly two centuries, a testament to both its practical virtues and the enduring appeal of its clever namesake.”
