Learn about 23 perennials for clay soil that are easy to grow and make your flower garden easy to maintain and beautiful.
The type of soil you have makes all the difference when you are creating or growing an ornamental garden. In my neck of the woods, here in Southwestern Pennsylvania, most of us have clay soil.

That often means we need to add organic material to our gardens to help aerate the soil and break up the clay. Natural mulch and compost are two great ways to help with clay soil.
However, there are many plants that will thrive in the clay, especially once they get established.
Below is a list of 23 perennials have I have grown successfully in clay soil, some for many years. Hopefully, they will offer some inspiration for your own garden.
I have also indicated the hardiness zone range they grow best in, and whether the plant prefers sun or shady conditions.

That's a pretty big list, right? There are actually more perennials that fit into this category. Asters, ornamental grasses and coral bells can also be planted in clay soil. So, as you can see there are plenty of perennials for clay soil to choose from so you can easily create a beautiful flower garden of your own.

Patti, this list is huge and wonderful!!! I saw a few of these plants down at the Lady Bird Johnson Wildflower Center but it's nice to see even more. Will be trying some plants soon. 🙂
Thank you for the ideas,
Barb 🙂

You have the most informative ideas and tips for garden flowers. Thanks for sharing.
This crazy, intense desert weather and soil can make it difficult to enjoy gardening.
Thanks for your ideas.

This is such a great post, Patti. I love Shasta Daisies but I've never had any luck growing them! Pinning this one for future reference!

Clay soil here and there are days when I've had enough of it. The area we're looking to move in the future has sandy soil and I'm sure that will come with a list of obstacles as well.
Great list of plants and my grandma had forget me knots in her yard. She liked them because they covered a nice space and required little care. I personally love their foilage and the surprise of dainty blooms. When I get settled I hope to have a ground garden area where I can load it up with an assortment of blooming perennials. Have to check out that Japanese Anemome, it's beautiful.

Thank Carole. The truth is many of these plants will grow well in just about any garden. You may have an issue with the heat the further south you go. However, most do well up to zone 8 which is pretty warm.
