Cold, Colder, Coldest: Which Vegetables Overwinter in the Garden?

Part One: 14 degrees Fahrenheit

Vates kale overwintered in our garden. I’ve long been interested in how cold-tolerant various vegetables are. We had two nights at 14 degrees Fahrenheit (-10C) and several others in the teens in December. What survived? We have Tyee spinach under rowcover, and Vates kale. The senposai was still alive, but some of the midribs had brown streaks. Sadly we don’t have any leeks this winter, as we lacked enough workers to tend them in late summer. We had a nice bed of Deadon cabbage, and some small heads of Melissa savoy that missed the bulk harvest were also alive. The Gunma cabbage stumps had some leaves and tiny heads still alive, but the Tendersweet were history.
