Cephalocereus senilis (Old Man Cactus, old man of Mexico, bunny cactus)
Old man cactus is a slender, columnar succulent native to the rocky regions of central Mexico. It is densely covered with long, bristly, grayish white hairs that resemble those on the head of an elderly gentleman. These are pollinated by moths and bats and followed by pinkish red fruits.
