Despite its somewhat off-putting name, crown of thorns (Euphorbia milii) is a very pretty succulent plant that can bloom almost year-round, even indoors. The thick, bright green leaves grow along the new stem growth. The true flowers are small and green, surrounded by showy bracts in red, orange, pink, yellow, or white. Although crown of thorns can grow into a woody shrub, it is also an ideal houseplant for most homes. It likes the same room temperature that people enjoy and it can handle the lack of humidity prevalent in most homes during the winter. This slow-growing plant will grow into a shrub reaching 3-6 feet tall outdoors. As a houseplant, expect it to reach only about 2 feet in height.
