20 days baby, 40 days full size. Osaka Hardy is a Nature & Nurture Farm original. It began with Purple Osaka mustard growing in our hoophouse through 2 polar vortex winters 2014 & 2015 where outdoor temps reached -20°. We saved seeds from the survivors and we are very pleased with the result. Hardier in the cold than traditional ‘Purple Osaka,’ this variety has a diversity of leaf shapes and colors. Leaf colors range from deep purple to green with mottled purple and leaf shape from round to elongated. This variety adds to our collection of cold hardy seeds that don’t need a second layer of protection inside the hoophouse unless temperatures dip below -5°. Others include Grand Rapids lettuce, Abundant Bloomsdale Spinach, and Vit Mache. Great for gardeners with cold frames and low tunnels. As baby greens it adds liveliness (and a touch of spice) to monotone lettuce salad. Larger leaves are cooked as mustard greens.

Mustard greens can be grown in the spring, summer, and fall, though they prefer an air temperature range of 60 - 75° . Direct sow seeds outdoors 4/15 - 8/30. For baby greens, broadcast sow seeds ½” deep, 60 seeds per square foot. For mature leaves, sow seeds 1” apart in rows 18” apart. Days to germination: 4 - 10. Sow every 3 weeks for continuous harvest, or let them re-seed themselves to have low maintenance self-sowing, edible “weeds”. Keep well watered during hot weather. It can grow in part shade. Tolerant of light frosts.
