The Stevia plant has been grown and prized in South America for many centuries as the native Indians recognised and used the sweet properties of these plants leaves. The food sweetening potential of Stevia has now been recognised in many countries around the world and commercial processing techniques have been developed to extract the sweetness and add this to other ingredients to produce low sugar foods and artificial sweetening tablets. The plant has hairy green foliage and insignificant small white flowers, growing to around 25-35cm (10-14") in height, providing the leaves are not picked to trim the plant. Sow: March-July. Flowers: September-October. Height: 50cm.
