Crown of Thorns, aka Euphorbia milii, also known as Christ Plant, Christ Crown, and Rosa Corona Espinas, is a beautiful, thorny succulent plant that can bloom almost year-round, and is native to Madagascar. The true flowers are small and green and are surrounded by showy bracts in red, orange, pink, yellow, or white, that look like colourful petals. Since it is a succulent, it is very forgiving about water, is low maintenance and can thrive as an indoor plant.
