And we do have hot, dry Mediterranean-like summers here in Western 
Oregon in the valley, we don't all live on the coast ;-)  Also, it 
does very well back east too.  I saw some beautiful ones in Florida 
and my grandpa had them for years at his place in New Jersey.

This is probably why the one my dad planted in his yard in San Jose 
died; in bad location (fairly hard clay) and didn't get watered.  SW 
US must be the hardest place to have them escape in the wild because 
of the heat and water requirements.

There was one plant down the street from us growing right up through 
a crack in the street at the curb (they had a planted one too, 
probably a seed that washed down the driveway.

This all seems about right to me.  Nice summary, Paul
