Dunstan Chestnut Seeds | (Castanea dentata × Castanea mollissima)
Blight-resistant. Productive. Built for generations.
Castanea dentata x mollissima, the Dunstan Chestnut, is one of the most important nut trees you can grow in North America. This blight-resistant hybrid combines the size and flavor of the American Chestnut with the disease resistance of the Chinese Chestnut. Once nearly wiped out, the American Chestnut lineage lives on here, producing heavy crops of sweet, edible nuts that feed deer, turkey, bear, and people alike. If you are building a food forest, wildlife property, or homestead orchard, this tree belongs at the center of it.
- Blight-resistant hybrid combining American and Chinese Chestnut genetics
- Produces heavy annual crops of sweet, edible nuts
- One of the most valuable wildlife food sources in eastern North America
- Large-canopy shade tree with strong hardwood value
- Cold-hardy across a wide range of growing zones
Things You Probably Didn’t Know
It once dominated eastern forests.
Before the blight arrived in 1904, American Chestnuts made up nearly 25 percent of the eastern hardwood forest. A single tree could produce hundreds of pounds of nuts annually, feeding entire ecosystems and communities.
The roots never gave up.
Chestnut blight kills the above-ground tree but not the root system. Across the eastern US, old root systems still send up shoots. The Dunstan was bred to finally carry those genetics forward with resistance.
It’s one of the best wildlife plantings you can make.
Chestnuts drop earlier than acorns and are higher in carbohydrates, making them a preferred food source. Deer, turkey, bear, squirrel, and dozens of other species depend on them.
It’s nutritionally different from most nuts.
Chestnuts are low in fat and high in carbohydrates, closer to a grain than a typical nut. They have been ground into flour and used as a staple food for centuries.

FAQ
FAQ
Do you pre-stratify the seeds?
Most of our seeds are not pre-stratified. We ship them unstratified so you can control germination timing based on your local growing season. We sell to all 50 U.S. states and Canadian provinces, and since each region has different planting windows, pre-stratifying would risk seeds germinating in transit or before you're ready to plant.
True stratification requires cold, moist conditions, which can lead to premature sprouting or mold if not timed properly. To avoid this, we store most seeds in dry cold conditions to preserve viability — but this does not initiate stratification.
Do any of your seeds need to stay moist? (Recalcitrant seeds)
Yes — some species we offer are recalcitrant, meaning they must remain moist to stay viable and cannot be dried out. Examples include: Chestnut, Hazelnut, Paw Paw, etc.
These seeds are shipped in moist cold storage and are clearly labeled on the product page when applicable. Please refrigerate immediately upon arrival and follow included care instructions.
Do you ship internationally?
We currently ship to the United States and Canada only. Unfortunately, we cannot ship to other countries without a phytosanitary certificate, which is required by most international customs agencies.
If you're interested in shipping outside North America, please contact us. Note that a phytosanitary certificate typically adds $60–$80 USD per seed type and must be arranged in advance.
