CEPHALOCEREUS

In this genus there are quite a few species, including those that are tall, erect, columnar, and generally woolly or hairy at the areoles. At flowering time the flowering areoles develop an additional mass of wool or hair often referred to as a pseudocephalium, which hides the small, bell-shaped or funnel-shaped flowers. The plants are of easy cultivation in full sunshine, and they are very popular with collectors.

Cephalocereus senilis. The best-known species of the genus, this is often called the “old man cactus”. It is a very attractive plant right from the seedling stage, though of slow growth. The stem is at first light green, becoming grey with age; the areoles are large, and the spines number 1 to 5. Along with the spines from each areole are developed from 20 to 30 long white hair-like soft bristles or hairs, which completely cover the plant.

Cephalocereus Hoppenstedtii. A very beautiful plant of slow growth and easy cultivation; a worthy companion to C. senilis.
