What Is Growing Within My Chokeberry Shrubs?

Question

I have several Chokeberry bushes along the side of my house. They are approximately 20 years old. Over the years a strange leafy plant has invaded the bushes. They appear to be a maple shape leaf. Could these have come from my mulch? They only grow intertwined in the bush.

Answer 1

It could be anything. Seeds get blown all over the place, plus seeds lie dormant in the ground for many years. It could come from the mulch, but look around your home, your neighbors', and see if you see the same thing growing elsewhere. It could be a native grape vine, such as a Vitus riparia.
