One of Nature’s Mysteries to Solve

Hey there!

Ever seen one of these?

mystery #166

 

I’ll check back later for your guesses!

It is a Chestnut bur–the name for the seed covering–as one of our readers guessed, but not a Horse Chestnut. Those are only a little prickly, not covered with spines like these chestnut burs. The chestnuts themselves are protected inside the burs.

These nuts don’t look like they fully ripened, but they were all that were left when we ran across them. Probably the local squirrels found and ate the best ones, because we squirrels will eat tree nuts of any kind–that is, once they are free from spines!

The nuts had also fallen from the burs still on the tree. We admit we aren’t quite sure which kind of chestnut tree this is. Nutmeg and I looked it up on The American Chestnut Foundation website and believe the leaves are wide enough the tree was probably an American Chestnut. But we also realize that is unusual. This tree was a good 30 feet high, but it was in a human’s yard, not the forest, so it was planted. Let’s hope whatever clever mix the human scientists used to keep this Chestnut from getting the Chestnut blight keeps working!

You can read more about work to restore the American Chestnut on The American Chestnut Foundation website. It’s so nice you humans are working to bring them back!
