Stevia rebaudiana |
Stevia rebaudiana is a plant species in the genus Stevia of the family Asteraceae. It is commonly known as candyleaf, sweetleaf or sugarleaf.[1][2]
It is a small seasonal plant which grows to a height of 30–60 centimetres (1–2 feet).[2] It has elongated leaves that grow along the stems and are lined up against each other. The flowers are typically trimmed to improve the taste of the leaves.[3] Stevia is a tender perennial native to parts of Brazil and Paraguay having humid, wet environments.[2][3]
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.[4] The chemical compounds that produce its sweetness are various steviol glycosides (mainly stevioside and rebaudioside), which have 200–300 times the sweetness of sugar.[2][5] Stevia leaves contain 9.1% stevioside and 3.8% rebaudioside A.[6]
