Agave in Vacation House Garden

Agave at Vacation HouseMay 19, 2010
There is a large cactus with a few baby cacti in the front garden of our vacation home.  It is an Agave that I think is Agave guiengola from the descriptions I found.  The leaves are thick, broad and triangular forming a rossette.  They have a bluish powder that gives the leaves a pale greenish grey colour.  The leaves have marginal spines that are quite small.
