Beta vulgaris subsp. cicla 'Fordhook Giant'
vegetableSwiss chard is a leafy beet relative grown for its large, glossy, crinkled green leaves and thick, succulent stalks, the Fordhook Giant strain bearing broad dark leaves on wide white stems. One of the most productive and forgiving greens, it tolerates both summer heat and light frost, yields for months from a single planting, and matures in about 55 to 60 days.

Direct sow or transplant from spring through midsummer in full sun to part shade and fertile, moist soil; like beets, each seedball gives several seedlings, so thin to about 6 to 12 inches apart. Keep moisture even for tender, fast growth, and chard will produce all season, standing through summer heat better than spinach and tolerating frost in fall.

Harvest the outer leaves and stalks once they reach full size by cutting or snapping them at the base, leaving the center to keep producing new leaves for months. Pick young leaves for salads and larger ones for cooking, and harvest regularly to keep the plant generating tender growth.
Swiss chard is very low in calories and extremely high in vitamins K and A and a good source of vitamin C, supplying magnesium, potassium, iron, and fiber, with thick white stems and midribs.
