Cacti and succulents
The species described here originate in the desert Southwest and Mexico; other species are native to those areas and/or other parts of the western U.S., the Great Plains, Canada, and Florida. Most species fall into one of two sorts: those having flat, broad joints (pads), and those having cylindrical joints. Though the use of common names is somewhat inconsistent, members of the first group are often called prickly pear; those in the second group are frequently known as cholla. Hardiness is variable. Flowers are generally large and showy. The fruit is a berry, often edible.Opuntia microdasys
