Old man cactus (Cephalocereus senilis)
Also known as: Old man of Mexico
Old man cactus (Cephalocereus senilis) is a cactus native to eastern Mexico. Old man cactus is widely cultivated in gardens and as a houseplant, resulting in dwindling numbers of old man cactus that grow in the wild. This species is popular due to its woolly appearance. Old man cactus grows best in well-drained soil and bright sunlight, which cause the hairlike fibers to grow.
