16 Plants for Wet Clay Soil and Shady Areas (Confirmed)

Wet clay and shade combined make for a difficult growing environment and only for the hardiest of plants. The good news is, many of these hardy plants are beautiful, edible, and very diverse in colors and textures.

Most are hardy to a wide range of growing zones, so a lot of room to play for design, colors, or general diversity is ahead.

I’ve made it my mission in this post to ensure all these plants can either grow in full or semi-shade and can definitely tolerate or thrive in wet conditions. Other choices you may see outside this post, may not actually do well in wet conditions.

Before planting any of these options check with your local invasive plant council or regional extension office for guidance on plants that may be invasive in your area.

When making your plant list, ensure each choice will be suitable for your further needs. Leave me a comment if you’d think specific information would be helpful to include for each plant. Or I’d even love to hear about what you’ll pick for planting!

I’ve stated the soil and sunlight selections for each plant as preferences do vary.

I think it’s important to include that in a post like this, because in the past when searching for my own plants for my own environment, I found articles that would post a description about the plant that said everything except for the information I was there for. I would look into each individual plant and find myself discovering that they aren’t actually ideal for my space. They didn’t match the title of the post, so I make sure that this won’t be the case on my blog!

Many (but not all) plants on this list I’ve tried in wet areas myself, and they are known to either grow well in shade or semi-shade (as specified). If you have further needs beyond wet clay soil in shade be sure to research your top picks for other factors such as pH and amend your soil accordingly!
