Chard, Swiss Chard, Silverbeet, Mangold
Chard is often called Swiss chard to distinguish it from French spinach varieties. It is closely related to beets, and a popular and productive garden vegetable. Steamed with a little rice vinegar, it is one of my favorite vegetables, producing all summer long.
Identification: Chard is a group of cultivars that are not found in the wild. Leaves are shiny, wrinkly (like spinach), with red or green ribs and more recently available in many colors (“rainbow chard”). Plants are 12-18" (30-45 cm) high.
