Days to Harvest: 50. This heirloom variety produces flat-toothed, grey-green leaves with a central purple stem. The colour intensifies as temperature decreases but turns a rich dark green when cooked. Sowing: Sow seed directly outdoors in a sunny site in mid spring when the soil has warmed but the weather is still cool. Comments: The vitamin rich leaves have a sot tender texture when braised or for use in salads. Good winter hardiness allows for long harvest. Approx. 400 sds/pkt.
