Cloves are the fruit of unopened flower buds of a tropical evergreen. The tree (Syzygium aromaticum) is native to Indonesia, but today is grown in other places including Sumatra, India, Brazil, Jamaica, and the West Indies. It reaches heights of at least 30 feet and produces white bell-shaped flowers which turn pink as they mature. The flower buds are hand-picked just before the flowers open. These harvested buds are then sun-dried, which turns then to a dark brown.
