As its common name suggests, the exotic African milk tree is native to West Africa, where it grows up to nine feet (2.7 meters tall) on the sun-beaten plains. This perennial succulent produces white blooms in spring and summer when grown outside in zones 9-10, though such displays are rare in the indoor plant. This is a great addition to your interior succulent display for its unusual and striking foliage. The upright stems grow in columns with small, paddle shaped leaves alternating with pairs of tiny thorns along the stem ridges. Varieties are available with green and white variegated stems or burgundy-red tinted stems and leaves.
Strong vertical lines and spiny textures give this succulent a modern, sculptural appeal. Likes lots of sunlight. A south or west facing window is ideal. Can grow quite tall, so well suited for large pots placed on the floor. Tall specimens are a perfect focal point for a large indoor cacti display. May be grown outdoors in warmer weather.
