Coriander is a member of the parsley (Apiaceae) family. It's an annual plant that grows on slender green stems. The plant can grow up to three feet tall and the leaves resemble parsley leaves.
When coriander flowers, it produces white flowers, with a hint of purple, and round, light brown seeds. These seeds can be harvested and used as spices. Coriander grows as a native plant around the world, specially in Sri Lanka.
