What color are the flowers? Yellow flowers might be Duchesnea indica - fruit is tasteless...

Here is a link that might be useful: D. indica

I second Duchesnea. The leaf tips are just a bit more round, the veins somewhat deeper and the foliage less shiny.
I had them mixed in my bed for a while and weeded out the Duchesnea.

It travels through a bed by stolons, IME harmless with taller species, I would not mix it with carpet plants or miniature Hostas.

And a "yup" from me on Duchesnea as well.

FYI - if you are curious about which wild strawberry species (F. vasca or F. virginiana), look for them when they are in flower. The height of the flower stem compared to the leaves is an easy ID key.
