update: The in ground was for a short period. The spot didnt have enough winter sun,and D.gigas quickly began to rot. Since then its been repotted and made a nice comeback.
Just night and day between how hardy its been in a pot and in ground. Touchy.

EDIT:After seeing this plant take everything thrown at it since 2004-except for a few winter days in 07- I have planted mine now in 2009. D.gigas might be rare,or expensive,or hard to propagate,but its an easy plant to grow outdoors in Z10b,10a,POSSIBLY 9b in those special inland soucal areas where a dip to below freezing is followed by 70f in winter.

This is a massive caudiciform plant native to an island off northern Africa (Socotra)... develops a fat trunk up to 2' in diameter in nature, but usually kept as a potted bonsai in the US and rarely gets even close to that size. Usually loses its leaves in winter when it should be kept really dry... water once leaves start coming back. Has weird, firm green flowers that are relatively small for a Dorstenia.
