Rose-hips. I didn't forage much since my last moving but I remember in autumn picking up pears from a single tree near my house. They went for underripe to extremely soft in just a few days and I didn't eat them only to learn afterward that it is normal for wild pear. What a disappointment!

In the city, you can forage tree leaves and also fruits. They are many essence we can eat that are not typically considered "fruit trees". But cherry, plum and haselnut tree are communs. Herbs, only in quiet place and only the head. That's the young leaves that are a only a few days old. I choose them in place when lawn are not mowed often so they are a not directly on the ground. And I park there is often different essences than the streets so you can find lots of fruit trees. Semi-build industrial area are also a great place to forrage. There is patches of countryside hidden inbetween ugly warehouse.

Neetles and blackberry are also available everywhere.
