Stenocereus is an easy to grow genus comprised of predominantly large, shrubby or tree-like columnar cacti. It is widespread from the Southern United States, throughout Mexico, Central America, the Caribbean, and into Northern South America. The genus name is derived from the Greek word stenos which means narrow and the Latin word cereus which means candle. The genus has been enlarged by the addition of species from several other genera. A close relative is the peculiar chinoa or chende cactus, Polaskia chende. Stenocereus species mostly flower at night and are pollinated by moths and bats. Some species, like Stenocereus martinezii, Stenocereus pruinosus and Sterberi bear delicious and refreshingly edible fruit similar to that of the Dragon Fruit Cactus, Hylocereus. They make excellent rockery plants and can also be grown in large pots. Stenocereus species are easy to grow and cold resistant to as low as -4°C, but only for short periods.

Stenocereus martinezii commonly known as Pitahayo or Pitayo is a tree-like cactus from Mexicos Sinaloa area, around Mazatlan. It grows up to 5 m in height. The stems have 9 ribs which are covered in areoles of 1 cm in diameter from which arise 3 central spines with the upper one up to 5 cm long and the lower ones about 5 mm long. Around those they have 7-11 short black lateral spines. From late spring to early summer it bears whitish pink nocturnal flowers which are followed by edible fruit. Synonyms for Stenocereus martinezii include Lemaireocereus martinezii and Rathbunia martinezii.
