I have a few questions. Is Autumn Revolution invasive? I'm in Alberta, CA. Will it thrive here? How poisonous are the berries?

Those are really good questions!

Autumn Revolution is a cultivar of American bittersweet and isn’t invasive. When shopping for bittersweet, be certain to avoid Oriental bittersweet (Celastrus orbiculatus). Autumn Revolution is cold hardy to USDA zone 2 while Oriental bittersweet is only cold hardy to zone 3. It should grow fine in your zone. I would plant it in the spring rather than fall to help get the roots established before winter sets in. And, mulch well. Though birds and squirrels enjoy the fruit, it is poisonous to humans and some pets including dogs.

Thanks for writing!
