Brightly colored flowers will attract attention to the garden. When planted en masse, think bright pink Coneflower or bright yellow Black-Eyed Susan, the effect can be absolutely stunning. Creeping Phlox has some brilliantly hued varieties to brighten spring. Use the daisy-like blooms of Blanket Flower to add a pop of summer color to a container. Tropical Hibiscus sports dinner plate sized blooms.
