Indian Sunflower Seeds

Sunflower seeds are the conical fruits of the sunflower (helianthus annuus), which belongs to the composite-flower family (compositae), and are approx. 7.5 - 17 mm long, 9 mm wide and 2 - 2.5 mm thick. Additional typical characteristics are their very light weight and their white, black or white and black striped coloring.
The sunflower comes originally from america, probably from mexico or peru. It is an annual composite-flower plant, growing to up to 3 m in height and having brown disc florets and yellow ray florets. The fruit husk and seed coat are fused together into a hard shell, which protects the embryo.
