British Cactus and Succulent Society

Dover Branch
For cactus and succulent enthusiasts of all ages and abilities

Cacti come in a wide range of shapes and sizes. The tallest is Pachycereus pringlei, with a maximum recorded height of 19.2 m, and the smallest is Blossfeldia liliputiana, only about 1 cm in diameter at maturity. Cactus flowers are large, and like the spines arise from distinctive features called areoles.

With a few exceptions, cacti are succulent plants and, like other succulents, they have a variety of adaptations that enable them to survive in hot and dry environments.
