Carnegiea is a majestic genus of large, columnar cacti native to the deserts of Arizona and northern Mexico, best known for the iconic Saguaro cactus. Characterized by its towering height, thick, ribbed body, and upward-reaching arms, it is a symbol of the American Southwest. An interesting fact is that Saguaros can live for over 150 years and produce beautiful, trumpet-shaped white flowers that attract pollinators, making them a magnificent centerpiece for any cactus collection or landscape.
