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. They are stored under dry, cold conditions to preserve viability without initiating stratification, allowing you to time germination for your local growing season.
The exception is recalcitrant seeds. Because these seeds must remain moist to stay viable, they are kept in moist, cold storage and are therefore in a pre-stratified state. Depending on how long a particular batch has been stored, some may arrive with an emerging radicle and be ready to plant immediately. Radicle development is not guaranteed.
Please refer to the individual product page and included growing instructions for species-specific requirements.
Do any of your seeds need to stay moist? (Recalcitrant seeds)
Yes. Some species we offer, including Chestnut, Hazelnut, and Paw Paw, are recalcitrant and must remain moist to stay viable.
Please refrigerate these seeds immediately upon arrival unless they have already developed a radicle. Seeds with an emerging radicle should be planted promptly.
Do you ship internationally?
No. We currently ship within the United States only.
We previously shipped to Canada, but tariffs, duties, and import fees resulted in customers receiving significant and unpredictable additional charges upon delivery. Because we cannot reliably calculate or absorb these costs, we have suspended shipping to Canada.
At this time, we do not ship to Canada or other international destinations.
