Stapeliads form part of the Apocynaceae family, formerly known as the Asclepiadaceae family. There are about 330 species distributed throughout the old-world countries. Stapeliads are easy to grow and make good collector’s items. They are often called the ‘orchids of the succulent world’ and there is an immense diversity in flowers, color, size and shape. The flowers are usually accompanied by a fetid or evil smell (hence the common name ‘Carrion flowers’), although some have a sweet honey smell.
