Q.Are Your Seriously Advocating That Your Readers Cultivate Porcelain Berry Vine?
This vine is partly spread by birds eating the fruit and spreading the seeds everywhere. There is no way a gardener can prevent this. Cultivating this vine is irresponsible and frankly, should be illegal. It is over running the local woodlands where we live on the Delaware/PA border. My HOA spends thousands of dollars per year to control it.

The article below does caution against growing the vigorous vine without checking first with the local extension about its invasiveness. It also says there is a cultivar that is not so invasive.
