They are often solitary, rarely offsetting, or producing stolons. All Notocactus are slow growing plants and make excellent house plants. They are globular to low columnar with characteristically depressed centers, usually many ribs, and usually many fine spines. They tend to be fairly short growing plants, but some species can reach 3 feet (90 cm), with cylindrical and spherical stems which are rarely branched. They are upright growing plants but may occasionally grow sideways with the top half looking as though it is wilting, this is less common that the upright growth and usually only occurs in old plants.The flowers usually last a week and tend to be yellow, in profusion, with red stigma lobes, and are borne on the upper "shoulders" of the plants in spring.
