Plant self-seeded in my yard.
I have a plant, actually several, with very large leaves 3ft. by 1.5 feet, shaped like an arrow, that has grown to about 7-8 feet and now has what looks like thistles seed-like growths. I have seen one in the park and elsewhere. My hunch it is a weed and I should get rid of it. Thanks.

Thanks for the info. After reading the material it very likely is burdock and I will seek to get rid of it before it flowers.
