This is a strange and stare-worthy succulent that stands out among the many. The stems do indeed look like worms, rings and all. They extend up and seem to wind, with rose and green colored leaves.
Care
Hardy, and can survive a light frost. Will require enough sun and not too much water. It will help to use a succulent soil. If kept in the direct sun for too long, they may scorch. Roots should not be drowned in water and should be allowed to drain, so use a pot that can do that.
