It is also known as the giant barrel cactus, golden barrel cactus, giant viznaga, or biznaga de dulce, and its Nahuatl (Aztec) name is huitzli nahual.. It is native to central Mexico in the Chihuahuan Desert. This species is the largest of the barrel cacti. In Mexico, its hairs are often used for weaving; and acitrón, a traditional Mexican candy, is produced by boiling the cactus pith.
