What about veronicas, Happy? They'd look nice. Kniphofia? There are some short ones that are nice. I have one that only gets about a foot tall and has light yellow blooms. That might be too much spiky stuff with the daylilies, though.

Blue rug junipers eventually get mangy and hollow out if you can't get to them to prune them every now and then.

Okay, here's some santolina photos I got this evening. This one is growing behind the pond. Colors are pretty accurate here except the button flowers are yellow, not white. I have tried and tried to get a photo that shows the flower color with no success.
