I have a flower bed that has been taken over by (presumably) a weed. It is a single short vine, the tallest is about 12 inches (maybe) the vine itself has a reddening color, deep green heart shaped leaves. It has a white peddled four peddled flower with a coned yellow stigma or eye (?). It is also has a noticeable aroma, some say it smells nice, some do not prefer it. Very hardy seems to like the moist conditions we've been experiencing.

The plant in your photo looks like Houttuynia cordata, chameleon plant, a groundcover. It does have the tendency to become invasive due to underground spreading rhizomes and needs to be controlled. To eradicate it, spray the foliage with an herbicide that contains glyphosate, such as Round-Up. The foliage of your ornamental plants would need to be protected because glyphosate is a non-selective herbicide and will kill any plant that gets the chemical on its leaves. Control will require persistence on your part. Otherwise handpulling is advisable but the rhizomes breakoff upon digging.
