or Swiss chard
Edible-leaf beet ( Beta vulgaris , variety cicla ), a variety of beet in which the tender leaves and leafstalks have become greatly developed.
They are a good source of vitamins A, B, and C. Chard is popular as a home-garden pot herb because it is easy to grow, productive, and tolerant of moderate heat. Highly perishable, it is difficult to ship to distant markets.
