Facts
Spanish translation, spinach: Las espinacas; Swiss chard: Las acelgas
Hmong translation: Zaub Ntsuab
Greens are a category of leafy vegetables. Beet greens, spinach, and Swiss chard are greens that belong to the same family of plants.
Contrary to the name, Swiss chard did not come from Switzerland. Swiss chard originates from a wild version of the beet that naturally grew in the Mediterranean and it was named by a Swiss botanist.
Spinach was the first frozen vegetable sold in North America.
Bright Lights is a popular variety of Swiss chard with colorful and bright stems.

Garden Connection
Planting
Greens are perfect for growing in school gardens! Growing greens in the fall is ideal because harvesting fits well with the academic calendar, but greens can be grown in the spring as well. Greens grown in the summer can taste bitter. Most greens (especially spinach) are quick growing, frost-tolerant, and generally easy to grow. Plant a variety of chard, spinach, and other greens to make a “salad garden”. Plant seeds directly in the garden.

Harvesting
Harvest spinach whenever the leaves are large enough to use, about 3-6 inches. Spinach is usually best if it is cut while young. Harvest chard while the leaves are young and tender or after they mature and are larger. Chard stems are edible too! Cut off outer leaves individually and let the inner leaves continue to grow for a future harvest.
