A compact rosette-forming succulent with broad, short, silver-blue leaves which have prominent purple-red teeth and terminal spines. Growing to 1 m in height by 1 m wide. 

I was particularly intrigued by the pattern that seemed to be 'carved' in to the leaf and decided to take a macro image to highlight that.  Agave parryi,Asparagaceae,Asparagales,Geotagged,Macro,Parry's Agave,United States,Winter,botany,flora

Appearance

The leaves are grey green and have a spine at the tip. One of the distinguishing features is that the point on the tip, which is typically dark tan, brown, or black, is darker than the leaf. Indentations of previous leaves show on the back of each leaf. The Huachuca variety grows in a rosette pattern as large as 2½ feet in diameter.

Because of its compact size, plus its low water use and low maintenance, Huachuca agave is considered a good landscaping plant for desert residential landscaping. It requires full sun. It is hardy to roughly −5 °F (−21 °C), though there are reports of specimens surviving temperatures at −20 °F (−29 °C).

Parry's agave is evergreen. Aged agave produce a twelve-foot stalk with bright yellow blooms. They then die after blooming, as all leaf and root resources are put into the stalk, flowers, and seeds. It can be propagated by either offset or seed.
