I had found these chestnuts a few weeks earlier on a walk through the park. I know there aren't any left now due to the obsessive cleaning by the park's people so I feel lucky to have found them when I did. Not that I needed more. Oh you know the routine. Every year you pick some up and put them in your pocket and they mingle with the ones you picked up the year before because you are now wearing your fall coat from last year. It's the same with autumn leaves, you pick some up and put them in your pocket and forget about them.
Anyway, these are the non-edible type of chestnuts... Horse Chestnuts or Aesculus hippocastanum and are not a true chestnut. Ha! Imposter! The true chestnut is Castanea and our favourite, the sweet chestnut, comes to mind Castanea sativa.
