To me Arugula is mostly a salad condiment. So in the past I have grown less of it than lettuce. But in recent years I have learned to appreciate this plant not just for its underestimated culinary potential beyond salads, but also it’s winter hardiness.
Arugula really has no problems with our winter weather. I grows very well over winter under fleece. In fact, it grows so well, and so lush, I have some difficulty harvesting it fast enough for our needs.
I find arugula will bolt and flower very quickly in spring here. So it is far better an autumn and winter crop than a spring crop.
