Milkweed sighting!

I had given up on this season for milkweed.  My coffee can effort didn't save those plants.  I have seen Monarchs fluttering around so I was content to let it grow somewhere else.  So to my surprise, I see a smallish plant this morning among the tall grass and weeds.  It's a small plant but the tallest I've had.  And I don't remember planting seeds there.  I did sow some last fall in hopes something would happen and I believe this is one of those seeds.

Here are some pictures that likely explain the trouble I've had this year (seem like record numbers this year)...

 

Here is the plant...
