Amsterdam is rich in plant species and many Amsterdammers enjoy taking care of plants in tree pits, tiny pavement gardens and other strips of reclaimed land. If only more of (all of!) the plants used could be edible or medicinal and that more urban gardeners knew how to harvest and use some of those amazing plants.
River of Herbs is an Amsterdam based community initiative that encourages and assists people to plant and use insect pollinated herbs throughout the city. This (English spoken) video provides a brief introduction to the work of River of Herbs by founder Lynn Shore.

That's a lovely video!
If you can wild forage in amsterdam, I guess you can anywhere, right?
