With the sunflowers, that is.
I cut down 3 a few days ago, anticipating looming disaster (which didn't happen, as it happens) and now I think I moved too soon. The seeds do fall out of the head without resistance but they aren't black streaked at all. And the seeds are small to my way of thinking. (especially considering these are the Giants)
So I've hung them all outside in the sun to see what will happen next. If birds start to feast on them, I'm giving them to the chickens.
The rest (12) are still out in the beds.
Looking silly, hanging upside down. But the seeds are all white still.
They may look dark, but that is only what is left of the stamens after the bees have done their thing
