Sisal (/ËsaÉªsÉl/ , [siËsal]), with the botanical name Agave sisalana, is a species of Agave native to southern Mexico but widely cultivated and naturalized in many other countries.t is sometimes referred to as sisal hemp, because for centuries hemp was a major source for fibre, and other fibre sources were named after it.
Sisal was used by the Aztecs and the Mayans to make crude fabrics and paper. In the 19th century, sisal cultivation spread to Florida, the Caribbean islands, and Brazil (Paraiba and Bahia), as well as to countries in Africa, notably Tanzania and Kenya, and Asia.
