Here are some more cacti I found in various Arizona places. These are all prickly pears, which are well-known as many bear edible fruit, sometimes referred to as cactus fruit, cactus fig, Indian fig, or tuna. Obviously, it must be peeled carefully to remove the small spines on the outer skin before consumption.
Plains prickly pear cactus can be found in rocky areas, pinyon-juniper forests, even Ponderosa Pine forests. There flowers bloom in yellow, pink or violet from May to July.
Desert prickly pear are found in rocky areas, as well as pinyon-juniper forests. They bloom from May to July. They have longer spikes than the plains prickly pear.
Porcupine prickly pear are found on rocky areas or hillsides in low elevation areas. They can be among pinyon-juniper and ponderosa pine forests. They have tiny flat spines, they bloom red and yellow flowers from March to June.
