The interesting Old Man cactus (Cephalocereus senilis) enthrals with its unusual look. Originally from Mexico, this cactus has a fluffy, old-man-like look from its long, white, hair-like spines. The spines both shield the cactus from herbivores and assist to insulate it against the strong desert heat. Rising to a height of 15 feet, the Old Man cactus is very amazing. With a thick layer of white hairs covering its cylindrical body, it can resemble a huge cotton ball rather nearly. This unique quality not only enhances its appeal but also is quite important for the survival of the plant. The hairs reflect sunlight, therefore lowering the risk of sunburn and enabling the cactus to retain its internal temperature. The Old Man cactus needs minimum water and thrives in rocky, well-drained soils in its natural habitat. It can go extended stretches without rain, therefore suited for the dry climate of the Mexican deserts. Watering helps it to survive during dry spells by absorbing moisture via its roots and storing it in its fleshy body. Usually white or yellow, the Old Man cactus blossom throughout the summer in magnificent, funnel-shaped form. These night-opening blossoms draw moths and bats, among other nighttime pollinators. Though they only endure a few days, the brief blossoms give the plant's whole look a striking visual component. The Old Man cactus has grown in popularity for indoor gardening and succulent collections because of its unusual appearance and rather little maintenance. Any lover of plants would benefit much from its quirky look and resilience.
