Trees for Wet Soil: 10 Species That Thrive Where Others Drown
Most trees die in waterlogged soil. Their roots need oxygen, and saturated soil doesn’t have any. Plant a typical nursery tree in a spot that stays wet after rain, and you’ll watch it slowly yellow, decline, and die over two or three years.
But some trees evolved in swamps, floodplains, and river bottoms. They developed specialized roots that function in saturated conditions. These are the trees you want for that low spot in your yard, the drainage easement, the area near the downspout, or the clay soil that holds water for days after every rain.
Wet soil vs standing water: an important distinction
Before choosing a tree, figure out what “wet” means in your situation:
Consistently moist soil stays damp most of the time but doesn’t pool. Most of the trees on this list handle this easily. You have the most options here.
Seasonally flooded soil pools water for days or weeks during rainy season but dries out in summer. Many trees tolerate this if they get a dry period between floods.
Permanently waterlogged soil is saturated year-round. Only a handful of species survive this. Bald cypress and willows are your main options.
Know the difference, because planting a “wet-tolerant” tree in permanent standing water will still kill most species on this list.
The 10 best trees for wet areas
1. Bald Cypress (Taxodium distichum)
The champion of wet sites. Bald cypress grows naturally in southern swamps with its roots submerged for months. Despite being a conifer, it’s deciduous, dropping its feathery needles in fall after they turn russet-orange.
- Zones: 4-11
- Mature size: 50-70 feet tall, 20-30 feet wide
- Growth rate: 12-24 inches per year (medium-fast)
- Tolerates: Standing water, seasonal flooding, heavy clay, drought once established
- Best for: Large yards, near ponds, drainage easements
The famous “knees” (woody projections from the roots) only develop in permanently flooded conditions. In a typical yard with occasional wet soil, you won’t get knees.
2. River Birch (Betula nigra)
River birch is the go-to tree for wet sites in the eastern US. It naturally grows along riverbanks and floodplains. The peeling, cinnamon-brown bark is gorgeous year-round, and it’s one of the few birches resistant to bronze birch borer.
- Zones: 4-9
- Mature size: 40-70 feet tall, 25-40 feet wide
- Growth rate: 24-36 inches per year (fast)
- Tolerates: Periodic flooding, wet clay, acidic soils
- Best for: Medium to large yards, naturalistic landscapes
‘Heritage’ and ‘Dura-Heat’ are the best cultivars. Both have superior bark color and better heat tolerance than the species. River birch does NOT do well in alkaline (high pH) soil. Test your soil pH before planting.
3. Red Maple (Acer rubrum)
Red maple grows almost everywhere in the eastern US, including swamps. It’s the tree with spectacular red fall color that lights up neighborhoods every October. Its tolerance for wet soil makes it one of the most versatile landscape trees available.
- Zones: 3-9
- Mature size: 40-60 feet tall, 30-50 feet wide
- Growth rate: 12-24 inches per year
- Tolerates: Wet clay, seasonal flooding, wide pH range
- Best for: Front yards, shade, fall color in wet areas
‘October Glory’ holds its leaves longer than other cultivars and colors up even in mild climates. ‘Red Sunset’ colors earliest and most reliably.
4. Willow Oak (Quercus phellos)
Willow oak tolerates wet soil better than most oaks. It has narrow, willow-like leaves (hence the name) that give it a finer texture than typical oaks. Fast-growing for an oak and produces less acorn mess than red or white oaks.
- Zones: 5-9
- Mature size: 40-60 feet tall, 30-40 feet wide
- Growth rate: 12-24 inches per year
- Tolerates: Wet clay, seasonal flooding, compacted soil
- Best for: Large properties, street trees, parks
5. Sweetbay Magnolia (Magnolia virginiana)
A smaller, more refined magnolia than the Southern Magnolia. Sweetbay grows naturally in swamps along the East Coast. Fragrant white flowers in late spring, silvery-backed leaves, and red seed pods that attract birds.
- Zones: 5-10
- Mature size: 15-35 feet tall (varies; evergreen in warm climates, deciduous in cold)
- Growth rate: 12-18 inches per year
- Tolerates: Wet soil, seasonal flooding, acidic conditions
- Best for: Small to medium yards, near patios, understory planting
The northern varieties (zones 5-6) stay smaller and lose their leaves. Southern varieties (zones 8-10) grow larger and keep their leaves year-round.
6. Tupelo / Black Gum (Nyssa sylvatica)
Tupelo has some of the most spectacular fall color of any North American tree: brilliant scarlet, orange, and purple, often on the same tree. It grows naturally in wet bottomlands and swamp edges.
- Zones: 3-9
- Mature size: 30-50 feet tall, 20-30 feet wide
- Growth rate: 12-18 inches per year
- Tolerates: Wet soil, acidic conditions, heavy clay
- Best for: Fall color in wet areas, specimen tree
Tupelo has a taproot, so buy it young (under 6 feet) and don’t try to transplant established trees.
7. Dawn Redwood (Metasequoia glyptostroboides)
A living fossil (thought to be extinct until rediscovered in China in 1941), dawn redwood grows fast and tolerates wet sites beautifully. Like bald cypress, it’s a deciduous conifer with feathery foliage that turns orange-brown in fall.
- Zones: 5-8
- Mature size: 70-100 feet tall, 25 feet wide
- Growth rate: 24-36 inches per year (fast)
- Tolerates: Wet soil, seasonal flooding, wide soil pH range
- Best for: Large properties, parks, specimen tree (needs space)
This tree gets enormous. Don’t plant it in a small yard. But if you have the room, it’s one of the most impressive trees you can grow.
8. Weeping Willow (Salix babylonica)
Willows are synonymous with water for good reason. They evolved to grow along streams and ponds, and their aggressive root systems actively seek moisture. That same root system means you should never plant a willow near sewer lines, septic systems, or foundations.
- Zones: 4-10
- Mature size: 30-40 feet tall and equally wide
- Growth rate: 36-48 inches per year (very fast)
- Tolerates: Standing water, flooding, almost any wet condition
- Best for: Large rural properties, near natural ponds, erosion control
Plant willows at least 50 feet from any underground pipes or structures. They’re beautiful but destructive. Check our list of trees to avoid near structures for more details.
9. Sweetgum (Liquidambar styraciflua)
Sweetgum produces outstanding fall color (purple, red, orange, yellow) and tolerates wet clay better than most shade trees. The catch: those spiky seed balls that litter the ground from fall through spring. If that bothers you, plant the fruitless cultivar ‘Rotundiloba’.
- Zones: 5-9
- Mature size: 60-80 feet tall, 40-50 feet wide
- Growth rate: 12-24 inches per year
- Tolerates: Wet clay, seasonal flooding, poor drainage
- Best for: Large properties where seed ball cleanup isn’t an issue (or use ‘Rotundiloba’)
10. Green Ash (Fraxinus pennsylvanica)
I need to mention Green Ash with a massive caveat. It’s one of the most flood-tolerant trees in North America and grows in nearly impossible conditions. But Emerald Ash Borer (EAB) has killed hundreds of millions of ash trees across the eastern US.
If you’re in an area with active EAB, do not plant ash. If you’re in the western US where EAB hasn’t arrived, it’s still a risk because the beetle is spreading. Consider bald cypress or river birch instead.
Trees to avoid in wet soil
These common landscape trees will die in poorly drained conditions:
- Most pines (especially Austrian, Scotch, and white pine)
- Colorado Blue Spruce (needs well-drained soil)
- Sugar Maple (prefers well-drained, slightly acidic soil)
- Most fruit trees (apples, cherries, peaches need drainage)
- Live Oak (ironically drought-tolerant but drowns in wet soil)
If you’re not sure about your drainage, do the percolation test: dig a 12-inch-deep hole, fill it with water, and time how long it takes to drain. If it takes more than 24 hours, you have poor drainage and need trees from this list.
How to improve drainage alongside tree planting
Planting the right tree is half the solution. You can also improve the site:
French drains redirect water away from problem areas. A 50-foot French drain with gravel and perforated pipe costs $1,500-3,000 installed, or $200-400 in materials for DIY.
Rain gardens are planted depressions designed to collect and absorb runoff. Plant your wet-tolerant trees in or near a rain garden and you solve two problems at once.
Raised planting works for trees that tolerate moist but not waterlogged conditions. Build up the planting area 12-18 inches above grade to improve root zone drainage while the surrounding area stays wet.
Grading the yard to direct water away from the house and toward a designated wet area gives you control. Hire a landscaping crew ($1,000-3,000) or rent a Bobcat for a weekend.
For tips on managing the area around your wet-soil trees once they’re established, our guide on landscaping around trees covers mulching and underplanting strategies that work well in moist conditions.
Planting tips for wet sites
- Plant in early spring when the soil is workable but before summer heat. Fall planting works too in zones 6+.
- Don’t amend the backfill. Use native soil when filling the planting hole. Amended soil creates a bathtub effect in clay.
- Plant high. Set the root flare 1-2 inches above grade. This keeps the crown out of standing water.
- Mulch wide, not deep. A 3-4 inch layer of mulch in a 4-6 foot ring helps regulate moisture. Keep mulch away from the trunk.
- Skip the fertilizer the first year. Let roots establish before pushing growth. Follow our tree fertilizer guide starting in year two.
Wet soil doesn’t mean you’re stuck with a bare yard. Some of the most beautiful trees in North America evolved in exactly these conditions. Pick the right species and you’ll have a landscape feature that turns a problem area into a conversation piece.
