Mixed Lettuce Leaves Seed Mats make it wonderfully simple to grow a colourful supply of fresh salad leaves in patio pots. Each pre-sown mat contains an equal mixture of Catalogna, Cocarde, Curled Red American, Grand Rapids, Salad Bowl Red and Rossa di Trento, removing the fiddly job of spacing individual seeds. Pick the tender leaves young for salads and sandwiches or allow them to grow larger, harvesting a few at a time so they can regrow for further cuts. The pack contains three 20cm seed mats with 137 seeds per mat.
