Big green leaves with frilly edges - Green Wave is great because it not only thrives in cool weather, but is also relatively tolerant of heat, so can be sown both in spring & after midsummer. Seeds from Real Seeds.
It is really, really impressively cold-hardy. Not only can you extend the season in a polytunnel, but also we find that plants left outdoors often overwinter perfectly well, making a good crop of leaves in spring.
Hot and spicy raw, tasty and mild cooked.
Sow after mid summer and harvest in autumn, winter and on into early spring. Also good grown overwinter in a tunnel. Sow in shallow drills, thinning to 15cm (eat the thinnings) or in modules and plant out. Water well in dry weather for nest results. Start harvesting when the plants reach 15cm, either cutting entire plants or harvesting leaves as required.
