Identification: new plant in garden might be sweet white clover -- pest?

Dear folks,

A beautiful, sprawling, white-flowered plant with a woody stem has appeared in one of our vegetable beds. The leaves are pinnate/obtuse, and serrate. The flowers have just appeared. They look like tiny white pea flowers. The stems when cut, have a rather strong sweet scent. The scent grows stronger as the plant dries. I'm guessing it's melilotus alba -- sweet white clover. I've read that this plant is great for honeybees, that it's planted all around the country for that purpose -- and that it's a nasty "alien" pest. We live on the edge of a state forest. I don't want to contribute some nasty invasive critter. Should I rip it out before it sets seeds?

This is my first post to this wonderful site.

Thanks!
Cynthia

 

Any chance of a photo? It does sound like you've identified it, but a photo would be useful to confirm.
