The kenaf (Hibiscus cannabinus) belongs to Malvaceae (the Mallow family). It is an annual herb that is probably native to the tropical areas of Asia or America, though its accurate natural origin is unknown. Nowadays, it is cultivated widely in the sub-tropical areas. This herb can reach 3-4 m in height in fall, if it is seeded a field in spring. The flowers are five-petaled, cream with dark rose-pink eyes and bloom from September to November. The fibers of stems are used to make cloths, ropes and pulps. This plant is also known for their contribution to the environment because of their ability to fix CO2 and to absorb nitrogen and phosphor compounds in water.
