Opuntia

Opuntia, commonly called the prickly pear cactus, is a genus of flowering plants in the cactus family Cactaceae, many known for their flavorful fruit and showy flowers. Between 8,000 and 9,000 years ago, the Opuntia prickly pear cactus was domesticated in central Mexico. Cacti are native to the Americas, and are well adapted to arid climates; however, they are still vulnerable to alterations in precipitation and temperature driven by climate change. The plant has been introduced to Australia, southern Europe, the Middle East, and parts of Africa.
