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.
