13 Native Tree Seeds to Plant in Delaware This Fall

Fall is one of the best times to start native trees from seed in Delaware. As temperatures cool and leaves begin to drop, many native tree species naturally release their seeds. Planting during this season allows winter weather to provide the cold, moist conditions many seeds need before they can germinate in spring.

Native trees are particularly valuable because they are adapted to regional growing conditions and provide food, shelter, and nesting habitat for local wildlife. Whether you want to establish shade trees, improve a wildlife garden, restore a natural area, or simply grow trees from seed, there are plenty of Delaware natives worth considering.

Here are 13 native tree seeds to plant in Delaware this fall.

1. White Oak

White oak (Quercus alba) is one of the most valuable native trees you can grow in Delaware. Mature trees develop broad crowns and can eventually become impressive shade trees.

White oak acorns mature in fall and generally germinate best when planted while fresh. Unlike many members of the red oak group, white oak acorns do not require a long period of cold stratification.

Plant the acorns about 1 to 2 inches deep in well-drained soil. Protect outdoor plantings from squirrels, chipmunks, and other animals that may dig them up.

Best for: Large yards, wildlife habitats, woodland restoration and shade.

2. Northern Red Oak

Northern red oak (Quercus rubra) is another excellent choice for fall seed planting. It grows relatively quickly for an oak and develops into a large shade tree with attractive fall foliage.

Fresh acorns can be planted outdoors in fall, allowing winter temperatures to provide the necessary cold stratification.

Choose healthy acorns without insect holes or obvious damage. Plant them approximately 1 to 2 inches deep.

Best for: Shade, large landscapes, woodland gardens and wildlife.

3. Black Oak

Black oak (Quercus velutina) is native to eastern North America and can be found in Delaware's forests and wooded areas.

Its acorns mature during fall and require a cold period before germination. Direct sowing outdoors allows nature to provide this treatment over winter.

Black oaks eventually become large trees, so plant seedlings where they will have plenty of room to mature.

Best for: Naturalized landscapes, wildlife plantings and woodland restoration.

4. American Beech

The American beech (Fagus grandifolia) is a beautiful native forest tree recognized by its smooth gray bark and broad canopy.

Beechnuts ripen in fall and can be collected when their prickly husks begin opening. The seeds benefit from cold, moist stratification.

Fall sowing is an easy way to provide these natural winter conditions. Plant the seeds shallowly and protect the area from rodents.

Best for: Woodland gardens, natural landscapes and wildlife habitat.

5. American Sycamore

Few native trees make a statement quite like the American sycamore (Platanus occidentalis). Mature trees can become enormous and are easily recognized by their distinctive mottled bark.

Sycamores produce round seed balls containing numerous small seeds. The seeds can be collected after the seed heads mature and begin drying.

Because sycamores naturally grow near rivers, streams and floodplains, they perform especially well in locations with consistently available moisture.

Best for: Large properties, stream banks, moist areas and naturalized landscapes.

6. Eastern Redbud

If you want a smaller native tree with spectacular spring flowers, consider Eastern redbud (Cercis canadensis).

Redbuds produce flat seed pods that mature during late summer and fall. Their hard seed coats create dormancy, so germination typically improves with scarification followed by cold stratification.

Seeds can be prepared and planted outdoors during fall so they experience winter conditions naturally.

Best for: Smaller yards, woodland edges, pollinator gardens and ornamental landscapes.

7. Flowering Dogwood

Flowering dogwood (Cornus florida) is famous for its beautiful spring display and colorful red fruits.

The seeds are contained inside the fruits that mature in late summer and fall. Remove the fleshy fruit material before sowing.

Dogwood seeds require an extended cold, moist period to overcome dormancy. Fall planting can provide those conditions naturally.

Flowering dogwoods generally perform best in well-drained soil with partial shade, although established trees can tolerate considerable sun when moisture is adequate.

Best for: Woodland gardens, smaller landscapes, wildlife gardens and ornamental plantings.

8. Black Cherry

Black cherry (Prunus serotina) is an important native tree for birds and other wildlife. Its fruits are consumed by numerous bird species, while the tree also serves as a host plant for native insects.

The pits have significant dormancy and usually need cold, moist stratification before they will germinate.

Seeds planted during fall can experience winter temperatures naturally, although germination can sometimes be irregular.

Best for: Wildlife gardens, naturalized properties, woodland edges and larger landscapes.

9. Persimmon

The American persimmon (Diospyros virginiana) is an especially interesting native tree to grow from seed.

Female trees can eventually produce orange fruits that become sweet when fully ripe. The fruits are also valuable food for wildlife.

Clean the seeds thoroughly after removing them from ripe fruit. Persimmon seeds benefit from several months of cold, moist stratification, making fall an excellent time for outdoor sowing.

Best for: Edible landscapes, wildlife gardens and naturalized areas.

10. Sweetgum

Sweetgum (Liquidambar styraciflua) is easily recognized by its star-shaped leaves and round, spiky seed capsules.

Its foliage can develop brilliant combinations of yellow, orange, red and purple during autumn. The small seeds generally benefit from a period of cold stratification.

Sweetgum can become a substantial tree, so give it plenty of room and avoid planting it immediately beside patios, sidewalks or heavily traveled areas where the fallen seed balls could become a nuisance.

Best for: Large landscapes, naturalized areas and fall color.

11. Tulip Poplar

Also called the tulip tree or yellow-poplar, Liriodendron tulipifera is one of the tallest native hardwood trees in eastern North America.

The tree produces cone-like clusters containing winged seeds in fall. Seeds generally require cold, moist stratification before germinating.

Tulip poplars grow quickly when young and perform particularly well in deep, fertile, moist but well-drained soil.

Best for: Large properties, shade, woodland restoration and pollinator habitat.

12. Eastern Red Cedar

Eastern red cedar (Juniperus virginiana) is a tough native evergreen that can handle conditions that challenge many other trees.

Female trees produce berry-like cones containing seeds. Germination can be slow because the seeds have complex dormancy and may need both warm and cold stratification.

Growing Eastern red cedar from seed requires patience, but seedlings can eventually become hardy trees useful for screening, wildlife cover and naturalized landscapes.

Best for: Privacy screens, windbreaks, bird habitat and difficult sites.

13. River Birch

River birch (Betula nigra) is a beautiful native tree especially suited to moist areas. Its peeling bark becomes one of its most attractive characteristics as the tree matures.

The extremely small seeds should be planted near the soil surface rather than buried deeply. Maintaining moisture is important during germination and early seedling development.

River birch is particularly useful in low areas or near ponds and streams where the soil remains consistently moist.

Best for: Rain gardens, stream banks, pond edges and moist landscapes.

Why Plant Delaware Native Trees?

Native trees offer benefits that go far beyond their appearance. They form an important part of the local ecosystem and can provide nectar, pollen, fruits, nuts, seeds, nesting locations and shelter.

Oaks are particularly valuable wildlife trees because they support large numbers of insects, which in turn provide food for birds and other animals. Fruit-producing trees such as persimmon, black cherry and flowering dogwood add another valuable food source.

Native species are also generally better suited to Delaware's climate than trees originating from dramatically different growing regions.

Tips for Planting Native Tree Seeds in Fall

When collecting seeds yourself, gather mature seeds from healthy trees and sow them as soon as appropriate for the species. Fresh seeds are often preferable to seeds that have been allowed to dry excessively.

Choose a well-drained seed-starting location and label each species. When planting directly outdoors, consider covering the seedbed with hardware cloth or another breathable protective barrier to discourage squirrels and rodents.

Avoid planting seeds too deeply. Large seeds and acorns can generally be covered with soil, while tiny seeds may need to remain close to the surface.

Most importantly, don't assume a seed has failed simply because it doesn't germinate immediately. Native tree seeds frequently have dormancy mechanisms that delay germination until environmental conditions are favorable.

Let Winter Do the Work

One of the biggest advantages of fall sowing is that Delaware's winter can perform much of the stratification work for you.

Seeds fall from native trees every autumn, spend winter exposed to cool and moist conditions, and germinate when temperatures rise. Gardeners can imitate this natural cycle by sowing suitable native species in fall.

From mighty white oaks and tulip poplars to colorful redbuds and flowering dogwoods, starting native trees from seed is an inexpensive and rewarding way to add trees to your property.

Planting a handful of seeds this fall could mean growing trees that provide shade, beauty and wildlife habitat for generations to come.
