Discussion

Agave desmettiana is an attractive and frequently cultivated plant, probably native to Sinaloa, Mexico. The species may be an ancient cultivar, possibly derived from A. sisalana or A. kewensis Jacobi. The plant reproduces only by vegetative means; capsules and seeds have never been seen. H. S. Gentry (1982) indicated that the plant produces a fine but weak fiber. In Mexico it is grown only as an ornamental.
