Native Plants for Clay Soil

Native plants that root happily into heavy clay — the dense, slow-draining soil that defeats so many garden-center perennials.

Tip: open your state below for the version of this list filtered to plants native to your region and hardy in your zone.
The plants

53 native species in this collection.

Heavy clay is actually fertile and moisture-holding; the trick is choosing plants whose deep, muscular roots can punch through it and even improve it over time. Avoid working clay when it is wet, plant a little high to keep crowns from sitting in water, and mulch to keep the surface from baking into a crust. These natives do the soil-building for you.
