Thanks very much,

Hello Prairie Girl,

It's definitely Hypericum, and likely Hypericum calycinum

 

Thank you so much for such a quick and accurate response. Btw, the "Prairie" in my name refers to that of Manitoba. But now I live in Germany.

Cheers,
Prairie Girl

 

Common name is Saint John's Wart not what is on your web ... Rose of sharon which is Hibiscus

 

Actually St. John's wort. Wort is a middle English word for herb or plant.
