Outdoor Winter Veggies in Mid-January

This is proof that winter vegetables can tolerate very cold temperatures.  We're in Zone 7 and although we've had an unusually mild winter, we've had cold nights.  Last night was mid-20's and tonight it'll dip down into the upper 10's.  Sara, my neighbor, planted her greens and herbs from Sow True seed last Fall and we've all been enjoying them since.  She has them in the backyard in a sunny spot and has recently began covering them overnight.  Thanks, Sara!!
