Like agave americana
, agave sisalana
is often grown as an ornamental plant, as well as being cultivated for its tough leaf fibers, used in ropemaking. The species grows wild in the US only in the Florida Keys; its origin is thought to be Chiapas in south Mexico, possibly a hybrid. The sword-like green leaves are long (35 to 34 inches), straight-edged, usually lacking any edge teeth, but tipped by a dark brown spine.
