Jumping Cholla is a cactus native to Sonora and the Southwestern United States.
The "jumping cholla" name comes from the ease with which the stems detach when brushed.
Often the merest touch will leave a person with bits of cactus hanging on their clothes
to be discovered later when either sitting or leaning on them. The ground around a mature
plant will often be covered with dead stems, and young plants are started from stems that
have fallen from the adult. They attach themselves to desert animals and are dispersed for
short distances.
