Agave × arizonica is a small plant about 30 cm high and 40 cm broad. Although similar to Agave utahensis, it has distinct differences in suckering more sparingly, in not forming a large dense clump, having leaves with a distinct dark brown margin and also more cylindrical flowers. Its flowers are yellow, with 10-20 per cluster, each up to 3.5 cm (1.4 in) long.[6][7]
