Chard, or Swiss Chard

Chard (Beta vulgaris var. cicla), also known as Swiss Chard, Silverbeet, Perpetual Spinach or Mangold, is a leaf vegetable, and is one of the cultivated descendants of the Sea Beet, Beta vulgaris subsp. maritima. While used for its leaves, it is in the same species as the garden beet, which is grown primarily for its roots.
Chard has shiny green ribbed leaves, with stems that range from white to yellow and red depending on the cultivar. It has a slightly bitter taste. The leaves are generally treated in the same way as spinach and the stems like asparagus. Fresh young chard can also be used raw in salads.
Modern cladistic botanical taxonomic systems such as that of the Angiosperm Phylogeny Group place chard and the other beets in family Amaranthaceae, but the older systems more likely to be encountered in horticultural sources place them in a family Chenopodiaceae.
