AKA Crown of thorns, Christ thorn

Crown of thorns is a favourite houseplant grown in warm climates as a garden shrub. They tirelessly appear almost all the year. It’s a hardy perennial with stout gray thorns and oval leaves that drop as they age. Its shoots, all surrounded by spiky thorns, are brownish and covered with small, oval leaves. The bright red, pink, white or yellow flowers grow on the shoot tips. Aside from the pure forms, there are many hybrids available.

Christ plant’s name is due to the resemblance between its branches and Christ’s crown of thorns.
