Help Identifying pink wildflower growing near water

[robrocke]

I live near Long Island Sound in coastal Connecticut and see this common wildflower frequently near and even in fresh/brackish water. It seems to have a lot of pollinator activity. Can anyone help me identify it? Thanks!

Looks like a lupine

Flower shape is wrong for lupine as is the foliage. Stems seem to be square which would point to a member of the mint family.

Yes, I concur.

Purple Loosestrife (Lythrum salicaria), in the Loosestrife family (Lythraceae), is considered native to much of Eurasia, and parts of northern Africa, eastern Australia, and Tasmania. However, it is considered an invasive exotic in North America where it can take over large areas of wetland habitat.
