Often listed either as Euphorbia symmetrica or totally swallowed up within E. obesa, this is a beautiful form of the plant. For now, we'll accept the monicker: Euphorbia obesa subsp. symmetrica. This is still a small plant but the markings are already impressive. From the first year we started growing succulents, back in ancient times ;), we've always kept this or one of it's cousins close at hand.
