Source for virginana "Virgin's Bower clematis

i have looked in all of the sources that I can find on line, no one has this plant. Does anyone have one to trade?????

annabelle, be careful in planting this! It can be very aggressive in your garden. I just wrote an article about a different variety of wild clematis, and learned a bit about this one in the process. I'd just encourage you to do your homework before you make a decision on planting this, and be sure to read the notes at the end of the Plant Files entry. It may be fine in your zone, or in the area you intend to plant it. . .or, you may find it takes over your entire yard! LOL
