Cilantro is a fast-growing, aromatic, annual herb that grows best in the cooler weather of spring and fall. This herb is used to flavor many recipes and the entire plant is edible, though the leaves and seeds are used most often.
Cilantro and coriander are different parts of the same plant. Cilantro, Coriandrum sativum, usually refers to the leaves of the plant, which are used as an herb. This describes the vegetative stage of the plant’s life cycle. Coriander refers to the seeds, which are typically ground and used as a spice. This happens after the plant flowers and develops seeds.
