To get a full season of color in your clay soil garden, plant flowers with a range of bloom times!
Plant early spring bloomers, such as Bearded Irises, Hepatica, and Creeping Phlox. This early spring display would then be joined with late spring to early summer blooming Indian Pink, Daylilies, Butterfly Bush, Helenium, and Echinacea.
For your shady garden, Hostas and Astilbes will give you a bright bloom in the early summer. The peak of summer would continue to add color from tall Panicle Plox, Black Eyed Susans, Blue and Red Cardinal Flower, and Bee Balm. With the end of summer comes the color of Sedum and Asters, which transition your garden to its autumn stage. Here, your summer garden is joined with more Bearded Iris (if you have reblooming varieties) and Liatris for your shade garden.The persistent blooms of Helenium and Echinacea will last through the cooling temperatures of late fall.
A garden filled with these clay loving plants will give you a colorful cottage-like garden that fills out more and more every year!
