Dioon species             

Currently 15 accepted names with several pending.  Species are all native to Mexico except one species found in Honduras.  Most Dioons are from Oaxaca with scattered populations in Veracruz, Chiapas, Queretero, Michoacan, Puebla, Sonora, and more.  When small plants Dioons are intimidating to identify and only take great form as adults.  Dioons are slow growing and take time to make impressive garden specimens.  When mature most Dioons rival the mightiest of African Encephalartos.  Many Dioons are relatively new to cultivation.
