This terrarium contains Opuntia, commonly called the prickly pear cactus, and Disocactus anguliger, also known as the fishbone cactus or zig zag cactus.
I photographed the prickly pear cactus during the fall at a public park in Austin, Texas, and I photographed the fishbone cactus at the home of a friend in London, England, during the summer.
