Prickly pear cactus

Prickly pear is native to the Americas. There are many varieties of prickly pear cacti, but the two common and naturalised varieties in New Zealand are Opunita monocantha and O. ficus-indica.
Prickly pear is also an invasive weed in Australia where it was introduced in the 18th century and used as natural agricultural fencing. It quickly colonised vast areas of farming land, sometimes driving farmers off their land.
