2014 My own photo taken mid September. Pictured are Beech Nuts at the side of the road, Stoneymeadow road, High Blantyre Junction with Dalton.
Beech is a fairly common hedgerow plant in the UK. Largely deciduous, the nuts appearing in Summer to Autumn are about 15mm long, forming 3 sides. The seeds are bitter to taste but known to be edible.
