About
Opuntia aciculata, also called Chenille pricklypear, old man's whiskers, and cowboy's red whiskers, is a perennial dicot and an attractive ornamental cactus native to Texas. It belongs to the genus Opuntia (prickly pear cacti). It is also widespread in Nuevo Leon and Tamaulipas (northern Mexico).
It was reported from Nuevo León, Mexico, according to D. Weniger in 1970. The specific name aciculata derives from many sources: the Latin word acicula which means "a small pin for a headdress". Chenille prickly pear, one of its vernacular names, comes for the fringe of spines around the edge of the pad. The specific name also means "covered with small pins".
Where it grows
It is native to Chihuahuan Desert (Texas) and northern Mexico.
Uses
The fruits are edible and the soft pads (nopales) can be cooked as vegetables. After burning of spines, the pads can serve as a good feed for cattle.
