Japanese anemones add a delicate charm to gardens with their tall stems and soft, flowing blooms. They grow well in clay soil, especially when it's kept slightly moist. Their late summer flowers offer a graceful pop of pink or white.
Virginia Bluebells (Mertensia virginica)
This native woodland beauty thrives in heavy, damp soil and brings stunning blue blooms in early spring. It’s a great choice for shaded or partially shaded clay areas. The plant goes dormant after blooming, so it pairs well with later-season growers.

Physostegia virginiana (Obedient Plant)
This upright perennial thrives in heavy clay and produces rows of pink or purple flowers that bloom from late summer into fall. It’s called the “obedient plant” because you can move its blooms and they stay in place. Great for filling in damp or difficult areas.
