For summer bloom, plant Japanese Anemone, Stoke?s Aster, Astilbe, Baby?s Breath, Balloon Flower, Butterfly Weed, Cardinal Flower, Lobelia, Black-eyed Susan, Shasta Daisy, Chrysanthemum, Daylily, Coralbell, Coreopsis, Gas Plant, Goldenrod, Ligularia, Lupine, Garden Phlox, Perennial Sunflower, Yarrow.
