Pacific Northwest Gardening: Seeking advice, 1 by bonehead

Here's my under deck bed. Full sun, western exposure. I like the color combo of shasta daisy, coreopsis, and soon to be blooming crocosmia. Stella daylily to the left of the bench. All good. BUT, the daisies are becoming over exuberant and instead of nicely being a backdrop to the coreopsis, they are now splitting and flopping over the top of the coreopsis, which are being overshadowed and will likely be fairly wimpy this year. This is a very generic shasta daisy, expands aggressively. Should I yard the daisies out and plant something a bit shorter? Cut it back earlier in the season? Thoughts and suggestions welcome.
