Like many gardeners in the Deep South, I grow leaf vegetables and greens during our mild winters as much for their beauty as for their taste—the lemon-yellow spikes of bolting mustard and collard provide luminous company for spring dandelions and daffodils. For many years, I’ve dismissed rainbow chard, with its bold greens, sassy yellows and reds, as gaudy, but this year, I decided I was just being a closet case and planted a plot of them. They thrived. Every time I pass them I feel like putting on a pair of heels and tossing glitter. Mix chard with spinach, bib lettuce and bok choy, dress with vinegar and oil.
