Answer: Perennials with heads of flowers, or with daisy-shaped flowers usually look better if at least some of the stem below the bloom is cut off, along with the faded flowers. This helps to avoid that unpopular "decapitated" look. Cut these back to a thicker main stem, where new buds are probably already forming. Perennials that respond well to this include Purple Coneflower (Echinacea), Shasta Daisies (Leucanthemum), Rudbeckia, Yarrow (Achillea), Blanket Flower (Gaillardia) and Beebalm (Monarda).
