Invasive vining plant

I live in Indiana.I planted two Loesener Bitteersweeet, Celastrus rostbornianus. I was told that Oriental bittersweeet, Celastrus orbiculatus is invasive and it would be best to destroy them. Are my plants considered invasive. I am assuming they are not native plant either.

Doug says that the Oriental Bittersweet (Celastrus orbiculatis) is invasive and a bit of a pain in the garden. Particularly in warmer areas where it doesn't get knocked back.

The native Bittersweet (Celastrus scandens) is not invasive. I love this plant for the edge of wild looking native perennial gardens and I note you need a male and female. This plant is being harvested too much in the wild and with disappearing habitat, it too is becoming harder and harder to find. (Grow it)


The one you're asking about Celastrus rosthornianus is also not considered invasive either. (yet) But you can argue that it isn't as nice as the native one. Given you've already planted this Chinese plant, my understanding is that it is hardy to USDA zone 5.
