Agave turneri, a recently described species, is found not far south of Mexicali in northeastern Baja California. Distribution is restricted to the eastern facing slopes of white monzogranite in the Cerro El Mayor and Sierra Cucupa. To date, small plants in 3-inch pots have survived winter lows in the 22-24 degree F range without suffering any damage. Plants seem to be a bit fussy when grown in containers, the watering should be monitored carefully to prevent fungal development, but not allowed to dry out for extended periods.
