We have a Norway Maple and it has not spread at all. I don't know how old it is, but it is at least 35. Our climate is so harsh that sometimes I like plants that are termed "invasive" thinking it might mean they will actually grow here. It took years before my mint decided to spread and it still is not terribly invasive.

Not just Alstro's, but others, too! Here's a neat example: A customer of mine was thankful that I was able to provide him with Norway Maples, a very weedy tree here, because he lives in a place they are not found. It might be a neat idea for us to start a list compilation of what we have, that are weeds, and basically keep a database so that people can request our weeds, without inundating Dell with weeds!
