Overview of Broccoli

Broccoli (Brassica oleracea var. italica) is a plant from the cabbage (Brassicaceae) family and was cultivated as a food plant thousands of years ago in Italy. The dark green part of the plant that we always associate with broccoli is in fact, the large flowering head of the plant, which is highly nutritious, and composed of numerous tiny green flower buds that have not opened yet. When they bloom, broccoli produces numerous small yellow flowers on its flower head.

Superficially, this flower head looks like the miniature crown of a small tree sprouting out from its thick green stalk, which itself looks like a miniature green tree trunk. The flower head and its stalk are surrounded by large leaves which are usually discarded when cooking broccoli. Broccoli is closely related to cauliflower, both being annuals. Today, there are many broccoli cultivars although they are look largely similar. Broccoli grows to between 0.5 to almost a meter in height when mature.
