Agave rzedowskiana is a recently described species found in Jalisco in western Mexico. The species is in the Striatae group but is geographically separated from the other members. The two closest members of the group, based on floral morphology, appear to be Agave dasylirioides and Agave petrophila. Plants form small rosettes to about 15 inches tall and 24 inches across, and, over time, will develop small clusters of rosettes. This clustering habit separates Agave rzedowskiana from Agave dasylirioides, and the wider leaves will be a key in distinguishing it from Agave petrophila.
