Don't hold your breath Vickie, I thought the same thing and it seemed to work for about a decade, since then (last several years) it has been attempting to take over. It's a never ending spring, summer, and fall chore to try to limit it's territorial spread. The last few years it's been ascending a tree, that is admittedly, pretty neat. It's gone up 20 to 30 feet. It does smell well and attracts bees (esp. honey bees) by the droves.
Your's looks impressive Jennifer.
