As they wither, the sunflower and stem start leaning over, as you can see here the 3 are headed south. I planted a wooden stake in the container and trussed them all up together. To keep the stake upright, I tied it off to the iron hanging planter in the middle of that patch of comfrey. The stems still seem a bit top heavy.
So far, only 1 seed head. The seeds don't taste like much though. I think the birds have been pilfering the seeds. This plant isn't grown for it's seed heads, apparently.
Weather today was mild, in the 70s, a bit cloudy by afternoon.
