Rainbow Bush, Mini Jade, Spekboom, or Elephant Bush (Portulacaria afra f. variegata) (Jacquin): This stemmed succulent is particularly versatile and easy to grow. Plant it outdoors in warm climates and it can grow into a dense, 4.0' tall shrub. Keep it indoors in a small pot and it will stay a petite, bonsai plant. It is native to South Africa and Swaziland where it grows on sunny, rocky slopes. It even has a symbiotic relationship with elephants: elephants eat some of the branches and their trampling aids propagation of new shrubs from stem cuttings.

P. afra variegata stands out for its green and cream leaves (0.5" - 1.0") and deep red stems that verge on purple. Planted outdoors, it grows as a cascading ground cover and eventually mounds upon itself into a shrub up to 4.0' tall. Though reluctant to bloom in cultivation, P. afra can sometimes produce clusters of tiny, violet flowers in midsummer.
