Could not upload a photo to my original post

that`s a tricky one

first I thought Caryopteris, but I think, the leaves should be decussate,

gut reaction was Gaura, but then the foliage is not really right either

perhaps someone else can chime in

Oenothera biennis?

I know I didn't buy any of those. Gaura is an annual here. Not oenothera either. Have had that before, and would not seek it out again.

I was hoping it was a daisy. But I think those leaves are darker and more toothy.

Did you plant any Asclepias tuberosa, butterfly weed?

Not any Asclepias because the leaves aren’t opposite.

my first ideas was the same as floral’s, Oenothera biennis.
