    THUG ALERT! Even cutting it completely to the ground in early spring didn't stop it from taking over a trellis to either side in addition to its own space. When I put it in, I also didn't realize it was invasive -- and there's just no way to deadhead every bloom. I dug mine up, threw it out, and I'm still pulling seedlings out here and there 3 years later.

    2021 update. still pulling out one or two seedlings each year!

    This plant is horribly invasive in our neighborhood in the South Carolina Lowcountry. There is a large bank of plants in an untended wetland area a block away, and I see seedlings all over the neighborhood. We are frequently trying to pry out seedlings from all over our front and back yards, which is very difficult; we don't like to use herbicides.

    This is one of my least favorite weeds; Japanese Honeysuckle and Thorny Olive are harder to get rid of, but at least they smell nice.

    A large number of conventional nurseries in the Midwest and East of the US do sell some of this Japanese vine in pots. It is pretty, but it is powerfully aggressive, grows super fast, and is also invasive to wild areas. One plant can self-sow around the yard a lot and into the neighbours' yards also, and the seedlings are not easy to dig out. It does have a stronger fragrance and heavier bloom than the similar, but less aggressive Virgin's-Bower Clematis (Clematis virginiana) that is native to much of the eastern half of the US. I have the latter and she is dioecious, having separate male & female plants, and is not making babies. Check out the entry of Clematis virginiana to see the difference.

    In my Zone 5, I cut almost down to ground in the Spring. I line a border with very thin branches (angled) for several sprouts to vine around.
