Heirloom Vegetable. Here is a miniature butterhead type lettuce about the size of a tennis ball that is ideal for individual salads. Dark green fleshy leaves wrap around a creamy yellow mild flavoured interior. Tom Thumb tolerates high temperatures and resists bolting. This often overlooked lettuce has been grown for over 150 years – that should tell you how good it is!
How to Grow
880 seed/gram Lettuce is a sun-loving cool weather crop that grows best in organic, well drained soil. Sow as soon as the soil can be worked in the spring, then every two weeks thereafter to ensure a continuous supply. Sow about 3 mm (1/8″) deep in rows 45 cm (18″) apart then thin to 25-30 cm (10-12″) apart in the row. An even supply of moisture during the entire growth period is imperative for success. Harvest head lettuce by cutting the head off at the base just below the lower leaves. Once lettuce bolts (starts to produce a rapidly growing flower stem) leaves become bitter.
