Wow! I asked for information and I got it! Thank you very much Ken. I'm thinking of planting it in an arched area by our shed (pics on my profile) between vybernums. Is it an aggressive ground cover, will it want to rule the world, or is it workable as long as I incorporate a restraining border (bricks?)

Its Latin name is Galium odoratum, by the way. It is not that invasive in our garden, but then it does have to comepte with a lot of other things.
