Anne writes of the first photo, "This wildflower is also known as common silverweed, Indian sweet potato, and silverweed cinquefoil. This is a native, common, low-creeping plant that spreads with long, red runners. Makes excellent ground cover – for those who don’t like to mow lawns : ) Seen a few days ago at the Glenbow Ranch Provincial Park, north west of Calgary."
Argentina anserina is perennial in the rose family. It is found throughout the temperate Northern Hemisphere. Research in the 1990s led to a name change for this species from Potentilla anserina, but it appears the jury is still out, because this has not been accepted by several online databases (GRIN, Flora of China).
