Confused by a Plant I Purchased

Question

I purchased what I thought was a Clematis, so the tag stated, over the summer. I have had Clematis before, and was a little confused by the leaves on this one. However, this plant began to get little tiny looking (seed size) buds on it in clusters. Nothing happened until the other day. I went out to water and found little pea size purple and pink berry looking things on it. What have I planted???

Answer 1

From what you've described, it sounds like porcelain berry. This article has description, culture and pictures: http://www.missouribotanicalgarden.org/gardens-gardening/your-garden/plant-finder/plant-details/kc/r350/ampelopsis-brevipedunculata-var.-maximowiczii-elegans.aspx
