Cos lettuce seeds for crisp upright heads
cos lettuce seeds are a classic choice for gardeners who want an upright, self-closing type with firm leaves and a clean, pale appearance. This variety is often grown as a romaine-style lettuce for the vegetable garden, producing neatly formed heads with a pleasantly crisp texture. As an annual leaf vegetable, it fits well into seasonal sowings and is suitable for both small plots and larger beds where uniform rows are preferred.
Botanical name: Lactuca sativa.
Ideal for open ground and under glass
These lettuce seeds for open ground are well suited to early and mid-season use, and they are also a practical option if you prefer to sow under glass lettuce for a protected start. The plant’s naturally self closing cos lettuce habit helps the leaves gather into a compact head, making it a reliable crisp leaf lettuce variety for everyday kitchen use. If you are looking for cos lettuce seeds for spring sowing or annual romaine lettuce seeds to diversify your leaf-crop selection, this cultivar offers a straightforward, traditional choice within the leafy vegetable category.
