Brassica rapa. Round leaves surround thick, white stalks of this oriental mustard. Mild, nutty flavor. Thrives in cold weather and is very drought hardy. Planted last winter in our courtyard garden as part of the NS/S greens mix, this winter it reseeded itself all across the gravel courtyard and hangs on in spite of the poor conditions. Approx. 1g/100 seeds per packet.
