About

Opuntia stenopetala is a species of cactus native to Mexico. It has no English name, though often the Spanish Tuna Colorada or Nopal Serrano are used. With flat stem-segments, it is one of the many prickly pear cacti belonging to the Cactus Family, the Cactaceae.

How to grow it

Opuntia stenopetala is regarded as a distinctive cactus suitable for xeriscaping, rock gardens and as a specimen plant in undertakings with a desert-like theme. It thrives in full sunlight, needs little water once established, and overall is low maintenance. It is generally pest-resistant, but can be susceptible to cochineal scale insects. Of course its sharp spines should be considered during placement.

Where it grows

Opuntia stenopetala is endemic just to Mexico. It occurs in the northern and central states of Aguascalientes, Coahuila, Durango, Guanajuato, Hidalgo, Nuevo León, Querétaro, San Luis Potosí, Tamaulipas, Veracruz and Zacatecas.
