Black Seeded Simpson Organic Lettuce Seeds 4090. Heirloom Vegetable. Approx. 1,000 seeds/pkt (880 seeds/gram).
Black Seeded Simpson is an old variety originating in 1875. It has been a favourite ever since! Extra large, wrinkled and crumpled bright green leaves are very appealing to both the eye and the palette. This lettuce is very well adapted to a wide range of growing conditions and it is one of the best to sow early and often!

While lettuce is fairly adaptable, it will make its best growth on organic, well-drained soils in sunny locations. Since lettuce is a cool weather crop, sow seed as soon as the soil can be worked in the spring then every two weeks thereafter to ensure a continuous supply. Sow seed about 3mm (1/8in) deep in rows 45cm (18in) apart. Lettuce can also be sown in blocks or squares as opposed to rows. Thin heading lettuce to 30cm (12in) spacing. An even supply of moisture during the entire growth period is imperative for success. Harvest leaf lettuce by either pulling the entire plant or by cutting leaves from the main stem at least 2.5cm (1in) above the base – this will allow the plant to sprout new leaves. Once lettuce bolts (starts to produce a rapidly growing flower stem), leaves will become bitter.
