There is no more doubt about the mystery plants. It’s a sunflower. Several sunflowers, that is. Everything about them says “Sunflower”: the broad leaves, the flat yellow disks, the mathematical spiral in the centers, the honeybee, the green Agapostemon bee, and more bees to come.
They’re about half the height of the giant sunflower that grew a couple summers ago, which was enough to drive to try to figure out what variety they are. Now I think the giant might have been come from the Large Grey Stripe that we eat. This current batch look more like the Black Oil Seed that the birds and squirrels eat. The only surprising thing is why I don’t find sunflower volunteers every year.
