I am having a problem with my snow in summer plants. They seem to sag and get brown in the center. I have them planted in an ideal location and I wonder if I am doing something wrong like overwatering?

Not a robust plant for me (Pacific NW), definitely not an invasive problem. I had it planted in dappled shade, moved it to full sun, still somewhat scraggly. Nice silvery foliage with white flowers, so I'm hoping the new location will perk it up.
