Queen of Thorns is a species of flowering plant from the Euphorbiaceae family. This plant is native to the desert regions of Mexico and Madagascar. In Europe, it was first introduced in France in 1821 and quickly gained popularity as a beautiful houseplant.
In the wild, Queen of Thorns can reach a height of 6.5 feet (2 m). It will grow up to 3 feet (1 m) tall if it is indoors. The sprouts are covered with thorns, hence the name. Legends say that the crown of thorns worn by Jesus Christ at his crucifixion was made from stems of this plant.
The true flowers are small and greenish, but bright red, orange, pink, yellow or write bracts surround them. After the flowering period, which sometimes lasts all year, the fruit appears. It has a form of a seed container with 3 grains.
