The story

Flax gave the world its first linen. It was domesticated in the Fertile Crescent about 9,000 years ago, and Egyptian mummies were wrapped in linen made from it. The seed, linseed, was eaten and pressed for oil, and still is.

Planting

Full sun, light drained soil. Sow thickly in early spring, a quarter inch deep, as soon as the ground can be worked.

Growing

Keep weeded while young; flax needs little water once up. Its sky-blue flowers open each morning and fall by afternoon. Grow it thickly for fibre and more widely spaced for seed.

Harvest and use

For seed, pull the plants when the bolls are brown, dry and thresh. Grind the seed fresh into porridge or bread. For fibre, pull earlier, soak (ret) the stems until the fibres loosen, then dry, break and comb.

What to watch for

Weeds early on; raw seed is best eaten ground or cooked, in moderation.
