I live in the neighborhood of Chestnut Hills. The actual tree that these quaint few streets are name after is around the corner or so I’m told. There is a Chestnut tree on my lot.. From my humble research which includes Google Lens and Plantnet, it is an American Chestnut. In the fall they drop their seeds. These seeds are encased in something that looks like a tennis ball with sharp spikes.

Last year I removed the seeds and planted them. To my surprise it has grown to about one and half feet tall and continues to grow looking healthy too. This year I planted about a dozen of these seeds and hope to have a small harvest over-winter.
