Pachycereus pringlei – Care Guide and Information
 
Pachycereus pringlei, also known as the Mexican Giant Cactus or Elephant Cactus, is an impressive columnar cactus native to the Sonoran Desert of Mexico. Often reaching heights of 20 meters and living for over 200 years, this cactus is one of the largest in the world. Its massive trunk, which can exceed 2 meters in diameter, is reminiscent of an elephant's leg with a smooth grey bark on mature specimens. The deeply fluted stems, adorned with blue-green to dark green ribs, expand and contract efficiently to store and manage water in the harsh desert climate. This cactus's commanding presence and architectural beauty make it a striking choice for enthusiasts with ample space.
