History: Burr Oaks are native to much of the central United States with populations in Canada stretching from Alberta to New Brunswick. The tree has been planted ornamentally across North America and the durable wood has uses such as flooring and barrels. The acorns, the largest in North America, are a source of food for many animals and indigenous peoples use the bark medicinally. Numerous towns and a book of poetry are named after this tree.
Why We Grow It:The Burr Oak's acorns have slightly less tannins than other oaks, making it the preferred choice for eating. It still requires processing to remove tannins, but once done, the nuts can be toasted, and/or made into flour and used in baking. It is one of the largest oaks in North America, making quite the specimen when full grown.
