The African Milk Tree (Euphorbia trigona) is native to Central Africa. It is often grown as a hedge there, useful for its rapid and enthusiastic growth, though its roots are not invasive. Though it looks a lot like a cactus, it is actually a succulent plant. It has many folk names, including candelabra cactus, cathedral cactus, friendship cactus, good luck plant, or good luck cactus (the good luck attribution is probably due to how quickly it grows, and how easily it propagates). It stays lush and green throughout its growing season, and new growth has a lighter green color than the base plant. The Rubra or Royal Red cultivar is very popular for its dramatic coloring: It takes on bright red accents later in the season.
