Kalette seeds

A cross between Brussels sprouts and kale, Britishbred kalettes look like mini cabbages with more delicate leaves. They have a sweet, nutty taste and can be eaten raw, fried, roasted or grilled and are good in pasta, stir fries and salads. Sow in March or April for harvesting in autumn. £1 for 25 seeds, johnsons-seeds.com.
