Albizia julibrissin*

This tree is exactly the kind of shape I'm looking for. Thank you for that
excellent suggestion. I like the idea also, because it would be something
different, yet would still look natural within the setting. I will
definitely investigate further.

A vaguely similar-shaped tree that I'm very interested in is prosopis
chilensis (Chilean mesquite), as found growing wild in Southern California
etc. I still haven't quite determined if it will grow easily over here - or
if it's even available in this country.
