Looks like a strawberry.

potentilla

Id say strawberry as well. . . ?

Potentilla sp. imo

definitely Potentilla

Potentilla since strawberry has only 3 leaflets in a cluster.

Thank you all. I'm going to look it up and upload newer photos today, since I found others similar to this one. potentilla a flower or a bush.

I know of some cinquefoil that are like a 1-2 ft tall perennial like P atrosanguinea, and some that are a creeping ground cover like P 'Nana'. There is also a bush form, Potentilla fruticosa, very common around here. I don't think you have the bush form. Some are weeds, or wildflowers, depending on your proclivities.

How about Astrantia?

Was this garden planted by somebody who knew something about perennials?

Not Astrantia. I agree that what we are seeing appears to be the work of someone who had some idea about plants.

Yes, and they had to move and I found it and now I'm learning about all these wonderful plants and hopefully I'll do good by them. Thank you all for your suggestions and help.
