Propagation can be carried out using seeds or cuttings. If you choose cuttings, you can use little branches, but wait until their wound dries completely up before putting them in soil.


The name of the genus Tephrocactus derives from Greek “Tephra” meaning “ash” which refers to the grayish color of epidermis. In Spanish T. Alexanderi is called “Bola de Indio”.
