The Crown of Thorns is a succulent plant native to Madagascar. It has thick, spiny stems and clusters of small, colorful flowers. The plant is drought-tolerant and can grow in various soil types. It is often cultivated as an ornamental plant, but it can also be invasive and toxic. The sap of the plant contains latex and irritants that can cause skin and eye irritation, and ingestion can result in vomiting and diarrhea. The plant is also known for its association with the biblical legend of the crown of thorns worn by Jesus during his crucifixion.
