Hi,

It is a wild strawberry and just produces these small fruits treasured by birds and other animals once a year in late spring. They are edible if you are not allergic to strawberries but keep in mind that it might be exposed to pollutants from vehicles or lawn pesticide applications. Also the flower is white not yellow. Buttercups, which are yellow and also have runners, are often found growing with wild strawberries. Buttercups are poisonous but do not produce red fruit.
