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 is a natural fiber derived from the long, green leaves of the 'agave sisalana' cactus plant. Sisal grows in semi-arid regions in Africa and Brazil. Sisal fibers (which can be up to three feet long) are sustainably harvested by hand from the leaves of the cactus plant. Sisal is not the same fiber as coir or jute.
