Celastrus scandens is hardy from Zone 3-8, you could try it, I have stuff overwinter with extra protection that is not hardy here, like Knifhofia and Rose of Sharon, to name a couple. Janet

I have a ton of bittersweet vines, they are coming up everywhere in my garden and I DO have both male and female , since I get flowers and berries, they are your's for the taking. Lone

To say that the oriental bittersweet is "invasive" is an understatement. That vine is a huge problem in my area and it has become the "kudzu" of the coastal northeast. It covers and kills large trees in my area, growing best where forest meets field. There are attempts at eradication but the only method is to kill everything and then start over with native plants. Perhaps the vine is much less aggressive in your colder zones? But I would not take the risk. I would not under any circumstances purchase and plant the non-native variety.
