It contains about 15 or so individual species but unlike the Pelargoniums, which are highly variable in form and habit, all Sarcocaulons are consistent in having fat succulent compressed stems with attractive semi-succulent leaves. Most species also possess a heavy armature of spines that are formed from the persistent hardened petioles. This is a protective feature that mimics cacti but they are not actual spines in the truest sense. Them Sarcocaulons can be considered as virtually indestructible and anyone can successfully grow them providing they receive full sun and plenty of moisture during their growing period. In cultivation they tend to grow primarily in the spring and fall but can also have several other short growth cycles throughout the year.
All species are slow growing with the very rare peniculinum being the slowest.
As a group they represent a unique place in succulent collections with some of the most beautiful flowers which last for several weeks. Many species are also aromatic. Rub their leaves and enjoy the spicy scent.
