Violet, not periwinkle. Probably common blue violet, viola sororia.

Some kind of vetch, which is indeed a pea relative. I don't know which specific type though.

Pretty! It looks like a skullcap to me, but I don't know what kind.

Thank you for the ID, Christine Y.

I will try to get rid of them. This is my first time growing milkweed, so it's the first time I've seen them in my garden.

Thank you SukanyaDatta.

Thanks FelipeRuhr.
