Beta vulgaris is a herbaceous biennial or, rarely, perennial plant with origins in Coastal Europe, N. Africa, W. Asia. Now naturalised in New Zealand.
It has leafy stems and grows to 1–2 m tall. The green leaves are heart-shaped, 5–20 cm long on wild plants (often much larger in cultivated plants).
The flowers are produced in dense spikes; each flower is very small, 3–5 mm diameter, green or tinged reddish, with five petals; they are wind pollinated. The fruit is a cluster of hard nutlets.
It has numerous cultivated varieties, the most well known of which is the root vegetable known as the beetroot or garden beet.
