Swiss chard is a colorful, nutrient-rich leafy green that thrives in Oklahoma’s mild spring and fall seasons. It’s heat-tolerant enough to keep going longer than most greens, and the vibrant stems add some serious flair to any garden bed. You can harvest it as baby greens or let it mature for bigger leaves. Keep cutting, and it’ll keep growing.
