They were the 'Street Tree' the developer gave to each lot in the neighborhood where I live. Everybody got one, but somehow I got two. Then we all just sat back and waited for them to split. My bigger one finally split last year and I paid a guy $$$ to cut it up and haul it away. Since then I've had suckers coming up from where it was. The other one has always had suckers coming up and it drops little berries on the ground. Ruby eats them as soon as they hit the ground, with no ill effect to date. They're usually pretty for anywhere from a couple days to a week, then I just wish they were gone. Never again.
