Answer: Your description is typical of Shasta daisy. It's the nature of the plant to send out only one flush of blossoms, regardless of deadheading. I prune the flowers off when they start to look wilted and before they start to decompose. Just to keep your garden neat, you should trim yours, too. While you're out there, cut a few new flowers to bring indoors. It makes the trip to the garden worthwhile!
