Not sure what kind of weed this is...it is not a milkweed.
Edited to add: Think I am going to have to eat my words. My North told me it might be Swamp Milkweed, sometimes known as Rose Milkweed. After a google search and looking at the images, I believe she is right. It doesn't have the big oval leaves of the milkweed I know...but guess I should have known it was some type of milkweed because the seeds look so similar.
Another song for you...
