Christ thorn

Is a species of flowering plant in the spurge familyEuphorbiaciae, native to Madagascar. 

It is a succulent subshrub or shrub growing to 1.8 m (5 ft 11 in) tall, with densely spiny stems. The straight, slender spines, up to 3 cm (1.2 in) long, help it scramble over other plants. The leaves are found mainly on new growth, and are up to 3.5 cm (1.4 in) long and 1.5 cm (0.59 in) broad. The flowers are small, subtended by a pair of conspicuous petal-like bracts, variably red, pink or white, up to 12 mm.

E. milii is not hardy, and does not tolerate temperatures below 10 °C (50 °F). In temperate areas it needs to be grown under glass in full sun. During the summer it may be placed outside in a sheltered spot, when all risk of frost is absent.
