Whether due to natural terrain and climate, or human effects such as stormwater runoff, some soil stays perpetually moist. If your soil is on the soggy side, you’ll first want to confirm that it’s not a situation that requires a sophisticated solution, such as installing a drainage system. Once that’s confirmed, then you can consider a more natural solution utilizing water tolerant plants.
Plants that thrive in wet conditions will help absorb excess water and the roots will hold soil in place to prevent erosion in sloped areas. There are many ornamental plants that can help solve your soil moisture problems and add beauty to your landscape at the same time.
Why Does Some Soil Stay Wet?
Along with the local climate, perpetually moist soil may be the result of various natural or human-caused factors, such as:
- Pavement runoff
- Compacted soil
- A high water table
- Nearby irrigation sprinkler head
- Natural springs
- Damaged irrigation or drainage pipe
When moisture varies across a property it can actually create some interesting gardening opportunities. Areas of wet soil are an advantage if you enjoy a diverse range of landscape plants. By choosing the right plants for wet areas, you can create a thriving plant community that appeals to a wider range of beneficial insects and birds, while managing your property’s excess moisture at the same time. Here are some moisture-loving, low-maintenance plants to consider when designing an ornamental planting for wet soil.
10 Plants That Can Tolerate Wet Soil
1. Pink Turtlehead
Native to the northeastern and southeastern US, pink turtlehead produces lovely pink flowers named for their resemblance to a turtle’s beak. Hummingbirds and butterflies like pink turtlehead nectar, while deer tend to leave the plant alone.
2. Black Chokeberry
To provide some food for your backyard birds, grow black chokeberry. This cold-tolerant shrub grows up to 12 feet (3.6 meters) tall and produces juicy dark berries that help sustain wintering birds such as cardinals.
3. Bog Rosemary
Bog rosemary is an evergreen shrub native to northern hemisphere bogs. A bog is a spongy, peat-bottomed wetland, but you can grow bog rosemary on your property if you have an area of moist, acidic soil. If you’ve got some nearly-swampy ground that you’d like to cover, bog rosemary may be a good choice. Just don’t mix it up with your edible plants–all parts of bog rosemary are highly toxic when consumed.
4. Black-Eyed Susan
Black-Eyed Susan is a charming yellow flower. It’s native to the eastern US and found in all 48 continental US states as well as every Canadian province–clearly a species that’s comfortable in a variety of settings. Soil for this plant should be well-drained but moist. Black-Eyed Susan is perfect in a semi-wild meadow plot in a wet-soil area.
5. Joe Pye Weed
Weeds are defined as valueless and unwanted. Joe Pye weed, therefore, is not a true weed but rather a lovely wildflower with lots of appeal for pollinators. Butterfly enthusiasts in USDA zones 3-9 should consider planting Joe Pye weed.
Large, daisy-like flowers burst forth from ligularia in the summertime. Damp soil and moderate sunshine provide perfect growing conditions for this bold and colorful plant that returns year after year.
7. Obedient Plant
Push an obedient plant flower to the side, and it’s known to simply remain in that position. Hence the name. Obedient plant makes lovely white or pink flowers that look a bit like snapdragons. The plant can spread invasively if left unchecked, so it’s best suited for large, naturalized areas or well-managed plots. Obedient plants also grow well in pots.
8. Cardinal Flower
(Lobelia x speciosa)
Cardinal flower is native to the American Midwest. It grows wild in wetlands but is cultivated easily in any damp soil. Long, red, tubular cardinal flowers are difficult for insects to pollinate. So, cardinal flower relies on hummingbirds for pollen transfer.
9. Cinnamon Fern
For a wet and shady spot where flowering plants struggle, creative landscapers can choose a non-traditional ornamental plant such as a fern. For an easily-managed fern species, try the cinnamon fern.
Cinnamon fern fronds can grow to five feet (1.5 meters) in length. Earlier in its life cycle, the fern appears as a coiled tip known as a fiddlehead. Many fiddleheads, including those from the cinnamon fern, are edible.
10. Dogwood Tree
Some bits of ground stay perpetually soggy due to an introduced water flow, such as a septic tank drain field. The right sort of water-tolerant plants, such as dogwood trees, can thrive in such spots while helping to stabilize the ground and manage excess moisture. Dogwoods have shallow roots, making them one of the safer tree choices around septic tanks or other structures.
Adapting To Your Local Plant Growing Conditions
Wet soil can be challenging to work with. But, water is the essence of life. Your soggy soil provides the opportunity for guilt-free cultivation of some lovely water-loving shrubs and flowers.
If your property’s storm water runoff creates an excessively wet bit of land, consider setting up a rain garden. It’s an eco-friendly landscaping feature that helps distribute surplus water while providing a haven for native pollinators and plants.
