Here’s a welcome sight in Amsterdam at the moment; the fruit of Potentilla indica (Barren strawberry) continue to look just like little strawberries on the floor of shady areas. They are not at all strawberries but they are edible and interesting. Step them in vodka or honey for an interesting drink and pudding accompaniment respectively.
Another tasty herb, Ground ivy (Glechoma hederacae). Can be used in place of mint for teas and some medicinal preparations.
