I don't grow this, but it does seem to be rather invasive in some 'wild areas of South-Eastern PA; the berries are quite lovely. Picture to be uploaded...
i work at a sanctuary in New York and the place is over run with this plant it is highly invasive there is almost nothing that can stop this plant it is killing off all of the native plants. it grows up anything it is near and will block out the sun from other plants. cutting it only kills off what is above what has grown and will do nothing to the roots and the roots go about 10ft below the ground so it is almost imposable to dig up. i recommend getting native plants like the trumpet honeysuckle.

Although this is a fairly attractive vine that looks like a grapevine, it is terribly invasive. It can and will choke out fully grown trees. I have seen several trees actually killed by this vine. It takes over the woods, it will cover buildings, and it can tear down fences. This may very well turn out to be the next "kudzu". And my local plant nursery sells it as an ornamental vine. Go figure.

WARNING!!!!! Please, please don't plant this vine. It's not that showy anyway, the berries are somewhat pretty and are the only pretty part. This vine is a NOXIOUS INVASIVE from Asia. It has choked out trees, bushes on my property and is poking through the screens on my house. I didn't plant it, but it's here anyway. Perhaps for some of these people where anything's hard to grow, (i.e. Arizona), it's not invasive, but it is everywhere else. It's ILLEGAL to plant in some states and for good reason. It has Kudzu-like potential, (Kudzu, the vine that ate the south.....). It's minor ornamental value is not worth battling its evil nature. It escapes into wild areas and CHOKES OUT NATIVE FLORA. It's berries readily re-seed, and before you know it, you'll have seedlings springing up all over the place, and going into the neighbors yard, and going into wild areas. Almost impossible to eradicate!!!!! PLEASE DON'T HELP SPREAD THIS NOXIOUS WEED!!!!!!!!!!!

In the arid mountains of Arizona it doesn't seem to be invasive. Mine (two) are about 4 years old. One, on south side under porch roof is growing in leaps and bounds but only started that last year. The other is on the west side so gets afternoon sun. It's much smaller but still healthy. My soil is clay. The winter birds love the berries.

Has small green flowers in July followed by round fruit that changes colors from green to darker shades of purple then to a porcelain blue (which is where it gets the name Porcelain vine or Porcelain berry).Often you have several colors of fruit at one time on the plant which makes it an unusual vine.Can become invasive.

Easily grown in average, medium wet, well-drained soil in sun or shade. Adapts well to most soils, including sandy or rocky ones. Avoid wet, poorly drained soils, however. Best flower and subsequent fruit production occur in full sun. Needs a support structure upon which to grow. Flowers on new growth, so this vine may be cut to the ground in late winter (optional) to control growth. Otherwise, trim stems as needed to maintain desired shape.
