Cool looking caudiciform S African succulent, usually grown in pots in So Cal (frost tender supposedely, but not sure how severely it's been tried- older plants are too expensive to experiment with). Slow growing woody caudex (trunk) to 10" in diameter topped off with bizzare, twisted dark green to purply, spiny branched succulent. Great collectors item. Uncommon.
