Native only to a small section of Oaxaca, Mexico, this monotypic genus is related to Corpyhantha and Mammillaria. Ortegocactus macdougallii is the only species, and an exceedingly rare greenish grey clumper. Though its now showing up in cultivation. The 1 to 1-1/2 inch heads offset profusely and these offsets can be used for propagation along with seeds. The plant is self fertile and only one is needed to produce fruits and seeds. The flowers come in spring or summer and are yellow. The picture below was taken in Mid April.
    Grow Ortegocactus in a fast draining mineral mix. Limestone chips are a good additive as the plant tends to like alkaline soils. Water moderately in summer and very carefully if at all in winter. The plant likes light shade to full sun.
