Beetroot

The swollen taproot of Beta vulgaris, a biennial in the Amaranthaceae family cultivated worldwide for its sweet, earthy root and edible greens.

History & Origins

Wild sea beet was foraged along Mediterranean and Atlantic coasts and used medicinally by the ancient Greeks and Romans, while the first cultivated forms—long, white, and carrot-shaped—appeared in Mesopotamian and Egyptian gardens of the 2nd millennium BCE. Selection for sweetness and pigmentation continued through medieval Arab horticulture and Italian Renaissance gardens, where the deep red, bulbous form familiar today was stabilized in the 16th–17th centuries.
