Euphorbia coerulescens (live succulent)
It is a medium-sized shrub with a number of upright branches that join at a single short stem, close to the ground. The stems are longitudinally ridged with four to six angles and paired thorns along the margins. Each branch is further constricted into segments of 4 – 8 cm long, reportedly reflecting periods of rapid and minimal growth. The stems are usually unbranched except at the tip.
