Wow, thank you folks, this is a great start. I did manage to identify the kind of spiraea we had, it was Spiraea Japonica, it's invasive, and one of those maps said it's been eradicated from Jersey. I think I know who helped it. The clown who bought the house from me; I drove by there a couple of months after the closing, and they had all been pulled up and dumped, and not replaced with anything. You know it didn't have anything to do with being invasive; this was 15 years ago, and the realtor had said that no one wanted property that had to be maintained, so get rid of landscaping.Of course, I didn't. You had to see what they did to the noble sycamore in the back yard, mangled it so they wouldn't have to rake leaves. Speaking of invasive species...some of them buy houses when they should be living in apartments.
