flowering kale

Looking like a giant, multipetaled, ruffled flower, this vegetable comes in colors that range from white to pink to purple, all encircled by curly green leaves. Flowering kale (Brassica oleracea), which is the oldest member of the cabbage family, has a slightly bitter taste and semicrisp texture. It's available from September through December. Choose heads with fresh-looking, brightly colored leaves with no sign of wilting. Refrigerate in a plastic bag for up to 5 days. See also kale.
