I don't have Boston ivy, but I do have Virginia creeper if that will help you.

I have tons of the stuff (at least that is what I think it is--I'll have to send you a pic to make sure). I have some sitting in a garbage can waiting to compost (so far nothing).

Oops. Looking at different pictures on the web, I think that I have English Ivy and not Boston Ivy. If you want that instead, I have tons. It grows on bricks, in the shade and has been green all year for me. good ground cover if you keep it in check. I have a yard that someone planted 20 years ago and then forgot that you had to maintain it, so everything is out of control here. I'm keeping some, but I have tons that has overgrown it's boundries. Let me know and I'll take some starts for you (if not, it goes to the compost pile)

Aww - It was really the fall color of the Boston that I was interested in. But thanks so much regardless!

Virginia creeper has the same color ... but may be more invasive.
