The Story

In the early days of the United States, millions of American Chestnut Trees grew across the land, from Michigan to Maine and south to Mississippi and northwestern Florida. The largest specimens were over 100 feet tall and had trunks 12 feet thick. The durable wood supplied people with the material to make furniture, railway ties, and utility poles. Then, in 1904, a deadly Chestnut blight from China appeared at the Bronx Zoo. By the time Nat King Cole was singing about roasting chestnuts in 1946, most of the country’s Chestnut Trees had fallen victim. We offer seedlings from mature, surviving Chestnut Trees in northwestern Illinois in an effort to help get this glorious species reestablished!

The Details

Colossal lives up to its name and will not disappoint in your landscape. The primarily planted chestnut in the U.S. today, Colossal is a fast-growing chestnut that produces an early-season yield of large nuts. Each nut has a sweet flavor after curing, and the flesh has a smooth texture to it, making it an excellent nut for snacking!

How to Grow

Colossal Chestnut appreciates good, rich, moist, well-drained soil and plenty of sunshine. Provide regular irrigation. Chestnuts are encased in prickly, sea urchin–like pods, so you’ll want to keep this tree away from patios, pools, sidewalks, and other places where bare feet may wander. In rural areas, semi-wild spaces are ideal, as local wildlife like turkeys, jays, and grouse will love to share in the bounty. Before planting, check with your local extension office about the presence of Chestnut blight in your area and the feasibility of planting Chestnuts on your property.
