Answer: Chrysanthemum frutescens, the marguerite daisy, grows as a perennial in warm winter climates and as annuals elsewhere. Your plants wouldn't survive a normal winter in the Pacific Northwest. But, since the weather has been so mild, they may have survived and might produce new foliage this year. Cut the stems down to 4"-6" above the ground and see if that doesn't encourage new growth. If you don't see any new growth within a week or two after pruning, it's time to replace your marguerite's.
