So many people these days are wondering about Hoodia. Well it's a genus in the Asclepiadaceae family which has about 20 species in the genus. The flowers are flat and saucer-like in shape and red, purple to brown or mottled dark yellow in colour. Flowers form prolifically near the stem tips in summer and emit a terrible stench, a smell of rotting flesh. The stems are many angled with white spikes appearing at short intervals on each angle. Stems are single or branch forming, and can have as many as 50 branches, they occur in variable shades of green. Since time immemorial, the succulent Hoodia has grown in the Kalahari desert in southern Africa and has been eaten by the San bushmen during their hunting trips. Now it's very famous worldwide.
