Euphorbia, commonly known as the crown of thorns, is a succulent, woody shrub with light green fleshy leaves, discrete flowers in racemes that are pointed by striking bracts in the shape of yellow or red petals and thick black spines (up to 1/2-inch long) that cover its water-retaining stems and branches.
Euphorbia is a genus of over 1, 600 species[1] in the Euphorbiaceae family. The common name refers to the notion that the crown of thorns worn at the crucifixion by Jesus Christ was crafted from this plant’s stem.
