I have had this plant for years. It's made of steel. Only recently I discovered that they have a gnarly tuberous root that can be raised for effect. I've left it hanging in a tree over winter and had most of the top growth die. In spring it just comes back.

Grown in strong light the patterning can become stronger and even turn reddish. Unlike some Caudiciform plants, stem cuttings will also produce the tuberous root. Makes a good hanging plant as the stems can become 18 inches long or more and trail down out of the pot.
