Crested euphorbias (back) are like something out of a monster movie. Grafted onto stems of another type of euphorbia, their
crests gradually double over as they grow. Other menacing creatures: Dyckia, a dark bromeliad (center), black mondo grass, and split rocks (Pleiospilos nelii ‘Royal Flush’), camouflaged as unassuming stones in black sand.
To grow: All four plants need mild temperatures and minimal water. They are happiest outside in arid, frost-free areas, but the succulents will thrive indoors too.
