This massive columnar cactus, known as the cardón, is from Baja California and Sonora, Mexico, where it assumes the same position in the ecosystem as the saguaro in Arizona. It differs from Carnegiea in terms of number of flutes on the stems (less) and fruit (dry). This is a slow growing species in terms of reaching the its typical size in the wild, but we find it a little faster than saguaros in Arizona. In addition, we have had no frost damage on our cardones at 18-20F. These plants are seedlings in 2-inch pots.
