Arugula is one of our favorite greens. It grows like crazy here and self seeds readily. In mild winters, it stays good enough to harvest through the whole cold season.
We planted this in the fall in a cold frame and it died way back when the temps fell to the minus teens. However, once the days start to lengthen and the temps warm up a bit, it greens right up and soon will be big enough to start harvesting.
In the meantime, now's a great time to plant a few more rows for harvesting later in the spring. If it bolts in the heat, let it go to seed and you'll find another row of it when the weather cools in August and September.
