Stevia rebaudiana is a plant species in the genus Stevia of the sunflower family (Asteraceae). It is commonly known as candyleaf, sweetleaf or Sugarloaf. It is a tender perennial native to humid, wet environments in Brazil and Paraguay.
Stevia rebaudiana is a small seasonal plant which grows to a height of 1–2 feet (30–61 cm). It has elongated leaves that grow along the stems and are lined up against each other. Flowers are typically trimmed to improve the taste of the leaves. Stevia is widely grown for its leaves, from which extracts can be manufactured as sweetener products known generically as stevia and sold under various trade names. The chemical compounds that produce its sweetness are various steviol glycosides (mainly stevioside and rebaudioside), which have 200–300 times the sweetness of sugar.
