About
Selenicereus spinulosus is a cactus species native to eastern Mexico and, possibly, the lower Rio Grande Valley of Texas in the United States. Common names include vine-like moonlight cactus and spiny moon cereus. Its specific name, spinulosus, means "with small spines" in Latin.
How to grow it
Plants ca 1 m long are capable of flowering. Give half-shade or full sun, and grow in a compost containing plenty of peat. During the growing period this plant needs ample water and regular doses of fertilizer. Fast growing and free flowering. Can be kept at 5 °C (41 °F) during winter, if kept dry. It is the easiest species to bring to flower in cultivation.
Where it grows
This species is found in eastern Mexico from Tamaulipas to Chiapas. Other sources claim that this species can be found in the states of Texas, Coahuila, Nuevo León and Tamaulipas. Plants were collected from the lower Rio Grande Valley of Texas in the United States, but this population may have been extirpated as it has not been seen outside of cultivation in some time. The specimen is commonly found growing on top of sun-exposed limestone outcrops as well as climbing on other plants in the sierra madre oriental hillsides and submontane matorral (scrub).
