Crown-of-thorns (Koeberlinia species; Euphorbia species)

Crown of thorns is a house and garden ornamental, native to Madagascar. It is named for a legend that identifies it as the plant from which Roman legionaries made the mock crown placed on Christ’s head at his crucifixion. In remembrance of the legend, the long stems of crown of thorns are sometimes deliberately trained to grow in a crown-like shape.
