Hi there! Not sure if this is the right place to ask this type of question, but we have a rather large plant growing in our garden and have been unable to identify it. Initially, we thought it was a giant sunflower but it's becoming clearer that we were wrong and now we want to make sure we haven't been cultivating something that isn't as friendly. The plant is currently about 12' tall. I've included a few pictures and can provide more if needed. Thanks for any advice you can provide. Mandy
