Is it Cactuses or Cacti?
Whatever the answer, you’ll find a lot of them at the Desert Botanical Gardens in Papago Park. The 140 acre botanical park was established at this site in 1939 by the Arizonza Cactus and Native Flora Society. The garden has more than 21,000 plants many of which are rare, endangered or threatened. Cactus describes a single plant and the plural is “cacti”.
