A grouping of these emerged in my perrenial bed this spring and quickly grew to over 3 ft tall. They have small pinkish flowers that appear to be growing right out of the stalk itself.
I’d like to know if this is a flower or a weed. It seems to be able to spread easily on its own.

    This looks like Motherwort (Leonurus cardiaca) — a medicinal herb.
