About
Stevia rebaudiana is a plant species in the genus Stevia of the family Asteraceae. It is commonly known as candyleaf, sweetleaf or sugarleaf.
It is a small seasonal plant which grows to a height of 30–60 centimetres (1–2 feet). 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. Stevia is a tender perennial native to parts of Brazil and Paraguay having humid, wet environments.
How to grow it
Beginning in the 1960s, commercial cultivation had spread to Japan, Southeast Asia and the US, but also in mildly tropical climates in hilly areas of Nepal or India (Assam region). The plant prefers warm, moist and sunny conditions. The plant cannot survive frost during the winter and therefore greenhouses are used to grow stevia in Europe.
Stevia rebaudiana is found in the wild in semiarid habitats ranging from grassland to mountain terrain, does produce seeds, but only a small percentage of the seeds germinate.
Uses
Stevia rebaudiana has been used for centuries by the Guaraní people of Brazil and Paraguay, who called it ka'a he'ẽ ("sweet herb"), to sweeten the local yerba mate tea, as medicine, and as a "sweet treat". Rural and indigenous populations in Paraguay also used the plant as a contraceptive.
