Kale Dwarf Blue Curled Organic
'Dwarf Blue Curled', from the 1800s, is extremely hardy and will overwinter in all but the coldest climates. Like most greens, it grows best in cool weather but will also withstand some heat. Leaves are rich in vitamins and minerals and low in calories. The flavor of the leaves is sweetened after a light frost; delicious in winter soups!
