This member of the Agavaceae
family was described by George Engelmann in 1875. It is found from the
south western US down to Northern Mexico, mainly between 900-2000 meters
elevation. It needs a well drained soil with little to some water
and lots of sun. The leaves will reach 40 centimetre the flower-stand
2,5 meters. The flowers are yellow, and beside by seeds, the plant can
be reproduced by offsets.
