Agave parryi var. parryi
A squat succulent that is ideal for collectors who love container gardens filled with interesting succulents. It is slow-growing, but is a lovely dwarf agave with grey-green to steel-blue, broad fleshy leaves that end in sharp black thorns.
This plant is extremely waterwise and fairly hardy, but in very cold areas it should be protected in winter. A parryi var. parryi is not always available, but is well worth the search.
