This is the groundcover..

We got it a few years ago, because we couldn't find any creeping phlox at the time. But this thing has really taken off, and when it's blooming it looks great.. it doesn't look so great at other times. ;) This year, the white flowers were present, but it also started having pink flowers. At any rate, we can't remember what it was called, or find it anywhere.

Can anyone help?

Oh, and just in case my image doesn't show up, the link is here http://www.paigelynn.org/gallery/Flowers2004/IMG_3559. You can also view a bigger version at this link by clicking on the picture. Sorry about the fence! It's the only picture I can find. :)

Thank you in advance!
