A. difformis have very ornamental banded and stripped leaves with contrasting white teeth.
 

Description:   Suckering succulent rosette , 45 cm in diameter and tall.
Leaves: Pale blue to grey-green straight with variable white teeth along leaf margins, but at least typically has a terminal spine that's very sharp. Each leaf characteristically have a broad creamy-green band down the centre of the  adaxial part (upper surface) of each leaf and dark green thin stripes in the abaxial (lower surface) of the leaf.
 

Cultivation:  Agave difformis is a relatively easy-to-grow species. Need  a very well-drained, soil. It is theoretically hardy to -7° C ,  particularly when dry .  It  grows fairly fast in summer if provided with copious water but allows to dry thoroughly before watering again. During the winter months, one should only water enough to keep the leaves from shrivelling. They do well in full sun or a lightly shaded area. Plants cultivated outdoors are drought tolerant and takes blasting heat and full sun.
 

Propagation: By suckers  which often are found growing around the base of the plant,  Remove the basal suckers (if available) in spring or summer and let the cuttings dry for a few days before inserting in compost or by seed.
