Plant Id

I'm visiting my mom in TN (zone 6-7) and she has a strange plant growing near her bird feeder garden. It is about waist tall and has large leaves, a thick stalk, and rather pretty trumpet shaped flowers. There are also strange spikey ball type things on the forks of the stalks. Does anyone know what this is? Thanks in advance!
