I received seeds from a friend. I referred to them as "yellow flower from Dot" because she didn't know what they were either.
They sprouted well and I planted them among the wildflowers in the alley. After inquires on this blog and with our horticulture agent, we have decided it is false sunflower. Most likely Heliopsis helianthoides.
I was surprised to find one of the plants is starting to bloom!
