Coriander Seed, Coriandrum sativum, is one of three plants that produces both a spice and an herb. The herb of the coriander plant is known as cilantro, while the fruit is known as coriander seed. An individual coriander plant can only be cultivated for one of these, as the cilantro leaves must be picked before the plant matures to produce the seeds. The fruit of the coriander plant contains two seeds which, when dried, are the parts that are used as the spice. The other two plants that produce both a spice and an herb are dill (dill seed and dill weed) and fenugreek (fenugreek seeds and fenugreek leaves).
Coriander is also called Cay rau mui or Ho tuy (Vietnamese), Coriandre (French), Koriander (German), Coriandolo (Italian), Coriandro (Spanish), Dhanyia (Indian), Hsiang Tsai (Chinese), Kizbara (Arabic) and Pak chi (Thai).
