In 2010 KSH supported the realization of a greenhouse project in Cevepar (64000m2) in Par-aguay. Stevia is a tender perennial native to parts of Brazil and Paraguay that favors humid, wet environments, although the root does not tolerate standing water. Paraguay is one of the main countries where Stevia rebaudiana or ka'a he'e (Guarani) is cultivated. Stevia is widely grown for its sweet leaves, which are the source of sweetener products. The leaves can be eaten fresh or put in teas and foods.
