Introduction to Prickly Pears
Prickly pears are native to the Americas, with the highest diversity found in Mexico and the southwestern United States. They are known for their flat, round pads (cladodes) that are covered in sharp spines and fine, hair-like glochids. The fruits of the prickly pear cactus, often referred to as tunas, are eaten fresh, used in jams and jellies, and even made into beverages. The pads themselves are also edible and can be cooked and eaten as a vegetable, known as nopal.
