Name this plant

Hi. I live in eastern ontario and I have a plant growing in my wild boar pen that is about 3' tall with large leaves, small yellow flowers and large poppy like seed pods growing from where the leaf joins the stem. Thanks to all for looking.

Abutilon theophrasti, a noxious weed.

 

Thanks a lot Ron B. It sure is one tough plant/weed.
