It is a small perennial shrub plant growing up to 65 cm, with sessile, oppositely arranged lanceolate to oblancoelate leaves, serrated above the middle. Trichome structures on the leaf surface are of two distinct sizes, one large (4-5 µm) and the other small (2.5 µm). It has small flowers (7-15 mm) of white colour arranged in an irregular cyme. The seed is an achene with a feathery pappus. Stevia plants can be propagated from cuttings or through seeds. Seed germination rate is poor and seedling establishment is very slow in this case. It is best grown as an annual or perennial transplanted crop. India being largest consumer of cane sugar along with largest diabetic population in the world, Stevia is ideally poised to make significant contribution in satisfying the Indian demand of natural low calories sweetener.
