This is a very
unusual plant that comes from Tanzania in south east Africa. It can be grown from seeds or cuttings. You are
better off trying the seeds, because I have tried the cuttings with little
success. As it grows, it can become more spherical with its strangely
rough and bumpy skin. It can grow to over one metre tall, with branches protruding
to around the same length. Rarely seen in commercial nurseries
circles in the UK, you can only obtain plants like these at specialist
succulent nurseries in Europe. Both photos were taken at the Palmengarten in Frankfurt in Germany.
