weeds around my potted clematis
I have a purple potted clematis with some English ivy. The problem is I have noticed some new different leaves which don't look like the clematis leaves or the ivy leaves. These leaves have tiny unopened lilac flowers at the end. Are these weeds? Because I bought this potted clematis, I don't know if it has something else in it as well. The new leaves, which I think are weeds, are growing quickly but their tiny flowers are few and unopened. Please help. Thank you for your time.
I can not tell what it is from this description.
If it came from a nursery it certainly could have been seeded with another plant.
