Prickly Pear Cactus

Description:

Prickly pears typically grow with flat, rounded cladodes (also called platyclades) armed with two kinds of spines; large, smooth, fixed spines and small, hairlike prickles called glochids, that easily penetrate skin and detach from the plant. — Wikipedia

Habitat:

Although prickly pear cactus can tolerate a wide range of temperature and moisture levels, it grows best in sunny, desert-like conditions. — Encyclopedia.com
