I feel dumb. I thought this was a sunflower but it’s not. What is that last item I’m missing?

The aine flower from polyamory sweet?

Edit: orthographe of the flower’s name

Are you using expansion mods? Or have you not updated to the latest version?
I’m on version 1.6.8 (steam) and can’t find the item in the shipping list.

I even installed smapi and used the item spawner mod and didn’t find the item, because of curiosity.
