Brassica 'Petit Posy Mix'™

Brassica oleracea

Interesting British breeding, a cross between the Kale and Brussels Sprouts species producing 'rosettes' of loose frilly edged buttons on a long stalk, in purples, greens and bicoloured leaves. However, the flavour and nutritional content of Brassica Petit Posy™ is akin to spring greens rather than Brussels sprouts - perfect for those who don't enjoy sprouts! Stands in condition throughout the winter, very winter hardy. The loose buttons are easy to pick off the stems and are perfect for adding to stir fries, serving steamed or microwaved and make very nutritious winter greens. One seed packet could produce enough crop to last up to five months supply.
