An image for Good Friday - [the plant Euphorbia Milii]
The common names [Crown of Thorns, Christ Plant, Christ Thorn] allude to the legend that the crown of thorns worn by Christ at the time of his crucifixion was made from stems of this plant. Interestingly, the stems of this plant are pliable and can be intertwined into a circle. There exists substantial evidence that the species, native to Madagascar, had been brought to the Middle East before the time of Christ.
"Then Pilate took Jesus and had him flogged. The soldiers twisted together a crown of thorns and put it on his head. They clothed him in a purple robe and went up to him again and again, saying, “Hail, king of the Jews!” And they slapped him in the face."
John Chapter 19 verses 1-3
