Cactus Succulent

A species of clump-forming succulent perennial up to 40cm tall with blue-grey to blue-purple, sausage-like striped stems with a waxy coating. During the winter, these sprout small tufts of green leaves which continue to grow in segments and flush purple depending on light levels. Curios rarely flower but if they do, flowers appear in autumn to winter after a period of dormancy. They are ray-less, white and inconspicuous with an unpleasant smell
