As with most invasives, they were imported, often from the Far East, sold for gardens and road banks. There are native species, but they do not "invade."
 
Please, please, either pull them out (easy with small, long shallow-rooted ones) or cut them down or off before the berries come. They completely take over and crowd out our native plants and young trees in fields and woods everywhere. There are quite a few on local lawns, private and business.  
 
If you don't want to take them out before the berries form (soon), at least cut off the prolific blossoms. Please! And spread the word. Thanks.
