13 Native Trees to Grow in Iowa This Fall

Fall is an excellent time to add native trees to an Iowa landscape. Cooler temperatures reduce stress on young trees, while the soil often remains warm enough for roots to continue developing before winter arrives. For gardeners growing trees from seed, fall also provides an opportunity to let nature supply the cold, moist conditions many native species need for germination.

Native trees are especially valuable because they are adapted to Iowa’s climate and growing conditions. Once established, many require less maintenance than poorly adapted species while providing food, shelter, and nesting habitat for birds and other wildlife.

Whether you want a towering shade tree, brilliant fall color, wildlife habitat, or a long-lived addition to your property, these 13 native Iowa trees are worth considering.

1. Bur Oak

Bur oak (Quercus macrocarpa) is one of the most recognizable native trees of Iowa. This rugged oak can tolerate drought, wind, cold winters, and a wide range of soil conditions once established.

Mature bur oaks can become massive trees, frequently reaching 60 to 80 feet tall with broad, spreading crowns. Their large acorns have distinctive fringed caps and provide an important food source for squirrels, deer, turkeys, and other wildlife.

Fall is an ideal time to sow fresh bur oak acorns outdoors. Unlike many other oak species, bur oak acorns generally do not require an extended cold stratification period before germinating.

Best for: Large yards, wildlife habitat, shade, naturalized areas, and long-term landscape planting.

2. Northern Red Oak

Northern red oak (Quercus rubra) is a popular choice for homeowners who want a large native shade tree with attractive autumn color.

Trees can grow approximately 60 to 75 feet tall under favorable conditions. The leaves typically develop shades of red, russet, and reddish brown during fall.

The acorns are also valuable to wildlife. When growing northern red oak from seed, planting acorns in fall allows winter conditions to provide the natural cold stratification needed before spring germination.

Best for: Shade trees, larger properties, woodland restoration, wildlife gardens, and fall color.

3. White Oak

Few native trees have the longevity and stately appearance of the white oak (Quercus alba). Mature specimens can live for centuries and develop broad, rounded crowns.

White oak leaves can turn beautiful shades of red, burgundy, and purple during autumn. Its acorns are especially valuable to wildlife because they tend to contain fewer bitter tannins than acorns from the red oak group.

Fresh white oak acorns should generally be planted soon after collection because they can begin developing roots during fall.

Best for: Large landscapes, wildlife properties, shade, woodland restoration, and legacy tree planting.

4. Shagbark Hickory

Shagbark hickory (Carya ovata) is famous for the long strips of bark that peel away from mature trunks, giving older trees their distinctive shaggy appearance.

The species commonly reaches 60 to 80 feet tall and produces edible hickory nuts. Those nuts are also an excellent food source for squirrels and other wildlife.

Fresh hickory nuts can be planted outdoors during fall, where winter provides the cold period necessary to help break seed dormancy.

Shagbark hickory grows relatively slowly, but its longevity, wildlife value, and distinctive appearance make it worth the wait.

Best for: Large properties, wildlife gardens, natural landscapes, and woodland plantings.

5. Black Walnut

Black walnut (Juglans nigra) is a valuable native hardwood found throughout much of Iowa. It can eventually reach 50 to 75 feet or more in height.

The trees produce large green fruits containing hard-shelled edible walnuts. Squirrels are particularly fond of the nuts and frequently carry and bury them throughout the landscape.

Black walnut seeds benefit from exposure to cold, moist winter conditions. Planting cleaned nuts during fall is one of the easiest ways to mimic their natural germination cycle.

Keep in mind that black walnut produces juglone, a naturally occurring compound that can inhibit the growth of certain sensitive plants nearby.

Best for: Large properties, wildlife habitat, nut production, timber plantings, and naturalized areas.

6. American Basswood

American basswood (Tilia americana), sometimes called American linden, is a large native shade tree with heart-shaped leaves and fragrant summer flowers.

Mature trees commonly grow 60 to 80 feet tall. Their small, nectar-rich flowers are extremely attractive to bees and other pollinating insects.

Basswood develops a broad canopy that can provide excellent summer shade. Its seeds have significant dormancy and can take time to germinate, making patience important when starting the species from seed.

Best for: Pollinator gardens, large yards, shade, woodland edges, and natural landscapes.

7. Hackberry

Hackberry (Celtis occidentalis) is an exceptionally adaptable native tree and an excellent choice for challenging locations.

Once established, it can tolerate drought, wind, urban conditions, and various soil types. Mature trees typically reach approximately 40 to 60 feet tall, although larger specimens are possible.

The small fruits ripen to shades of orange, red, or dark purple and provide food for numerous bird species.

Hackberry may not receive as much attention as maples and oaks, but its toughness and wildlife value make it an excellent Iowa landscape tree.

Best for: Wildlife gardens, urban landscapes, windbreaks, difficult sites, and shade.

8. Eastern Redbud

Eastern redbud (Cercis canadensis) is an attractive choice when you need something smaller than a towering oak or hickory.

Before its leaves appear in spring, branches become covered with clusters of pink to purplish-pink flowers. The heart-shaped leaves provide additional ornamental appeal throughout the growing season.

Redbuds commonly mature around 20 to 30 feet tall, making them suitable for smaller residential landscapes.

Seeds have a hard outer coating and typically benefit from scarification followed by cold stratification before germination.

Best for: Small yards, woodland edges, ornamental landscapes, pollinator gardens, and spring color.

9. American Sycamore

American sycamore (Platanus occidentalis) is a dramatic native tree best suited to properties with plenty of room.

Mature trees can reach 75 to 100 feet or more. One of their most striking characteristics is their mottled bark, which flakes away to reveal patches of cream, tan, gray, and greenish-white.

Sycamores naturally occur around streams, rivers, floodplains, and other areas with moist soils. They are particularly useful when a landscape has a large, damp area where smaller trees may struggle.

Best for: Large properties, stream banks, moist soils, naturalized landscapes, and dramatic shade trees.

10. Eastern Cottonwood

Eastern cottonwood (Populus deltoides) is one of the fastest-growing native trees in Iowa.

Under favorable conditions, young trees can put on several feet of growth per year and eventually exceed 80 feet in height. Cottonwoods naturally thrive around rivers, floodplains, and other moist locations.

Their rapid growth makes them useful where quick shade or a naturalized tree canopy is desired. However, their enormous mature size and extensive root systems mean they should be planted well away from houses, sidewalks, septic systems, and underground utilities.

Best for: Large rural properties, riverbanks, wet areas, wildlife habitat, and naturalized plantings.

11. American Elm

American elm (Ulmus americana) was once one of the defining shade trees of towns and cities throughout the Midwest.

Its graceful, vase-shaped canopy can reach approximately 60 to 80 feet tall. Unfortunately, Dutch elm disease devastated enormous numbers of American elms during the twentieth century.

The species remains an important native tree, and disease-tolerant selections are now available. American elms grow relatively quickly and adapt to a variety of soils.

Best for: Large yards, native landscapes, shade, restoration projects, and open spaces.

12. Black Cherry

Black cherry (Prunus serotina) is a native tree valued for wildlife habitat, attractive flowers, and high-quality wood.

Trees commonly grow 50 to 80 feet tall. Clusters of small white flowers appear during spring and are followed by dark fruits later in the season.

The cherries are eagerly consumed by birds, which help spread the seeds naturally. Seeds typically require cold, moist stratification before they will germinate, making fall sowing a convenient option.

Black cherry works particularly well along woodland edges and in naturalized landscapes.

Best for: Bird gardens, woodland edges, wildlife habitat, naturalized properties, and native tree collections.

13. Sugar Maple

Sugar maple (Acer saccharum) is an excellent choice for Iowa gardeners seeking spectacular autumn foliage.

Its leaves can develop brilliant combinations of yellow, orange, red, and sometimes deep reddish-orange during fall. Mature sugar maples commonly reach 60 to 75 feet tall and develop dense, attractive crowns.

Sugar maples generally prefer fertile, well-drained soils and perform best where they have adequate moisture. They are less tolerant of extreme heat, road salt, and severe soil compaction than some other native shade trees.

Seeds naturally fall in autumn and experience cold winter conditions before germinating in spring.

Best for: Fall color, shade, larger residential landscapes, woodland gardens, and traditional landscapes.

Why Plant Native Iowa Trees in the Fall?

Fall planting offers several advantages. Air temperatures are cooler, which means newly planted trees lose less moisture through their leaves. At the same time, soil temperatures can remain relatively warm, allowing root growth to continue after above-ground growth has slowed.

Fall is especially useful when growing native trees from seed.

Many Iowa tree species have evolved seeds that remain dormant until they experience winter. This process, commonly called cold stratification, helps prevent seeds from sprouting during an unusually warm period in late fall only to have tender seedlings killed by winter.

By sowing seeds outdoors in fall, gardeners can allow natural temperature and moisture changes to perform much of this work.

Tips for Growing Native Trees From Seed This Fall

When collecting or purchasing tree seeds, start with healthy, viable seeds from a reliable source. Research the germination requirements of each species because they can vary considerably.

Fresh acorns and nuts should generally be protected from squirrels, chipmunks, mice, and other animals. Hardware cloth or another breathable protective covering can help prevent wildlife from digging up planted seeds.

Mark planting locations carefully. Some tree seeds germinate quickly the following spring, while others can remain dormant longer.

For seeds planted in containers, make sure pots have excellent drainage and are protected from being overturned or completely drying out.

Most importantly, don't assume a seed has failed simply because it doesn't germinate immediately. Native tree seeds often operate according to seasonal cycles rather than a gardener's preferred schedule.

Choosing the Right Tree for Your Iowa Property

Before planting any tree, consider what it will look like 20, 40, or even 75 years from now.

A cottonwood or sycamore that seems small as a seedling can eventually become enormous. These species need significantly more space than redbuds or other smaller trees.

Consider mature height and spread, soil drainage, available sunlight, proximity to buildings and utilities, and the amount of maintenance you are willing to provide.

Matching the species to the location is one of the most important steps toward growing a healthy, long-lived tree.

Create a More Native Iowa Landscape

Planting native trees is an investment that can benefit a property for generations. A small acorn planted this fall could eventually become a massive oak providing shade, wildlife habitat, and brilliant seasonal color decades from now.

Bur oak, white oak, shagbark hickory, black walnut, hackberry, sugar maple, and the other native trees on this list each bring something different to the landscape.

You don't need to plant all 13. Start with the species that best match your soil, available space, and goals. Give them the right conditions and a little patience, and this fall's seeds and young trees could become some of the most impressive features on your property.
