To each its own season. The mainstay of my winter garden is chard, and it thrives in the cooler months. Not only that, in the winter, I don't worry about them bolting, a bad habit, which they will do in the summer. This plant was grown from seed on my balcony in late summer and transplanted.
Chard is underrated as a veggie. Lately, I chop chard leaves into little bits and throw them into warm soup at the last few minutes of cooking. In the summer, I saute minced garlic in extra virgin olive oil for a few moments until fragrant and then add chopped chard leaves until they wilt.
