Barren strawberry, Geum fragarioides, also referred to as Waldsteinia fragaroides
 
Barren strawberry is a low-growing evergreen groundcover with glossy leaves and flowers that resemble strawberries. It also blooms in May and June, but is golden and doesn't bear edible fruit. In ideal conditions, the plants spread by underground rhizomes and form a dense mat that turns bronze, copper and purple in winter. It is famous for growing in tough conditions, for example, dry, partial shade or under conifers. 
 
Growing conditions:
In the wild, barren strawberry is rare and, in many places, endangered. It is found on damp evergreen and deciduous forest edges, on wooded slopes, and on rocky sites. It prefers partial shade in moist, humus-rich, slightly acidic soil but is tolerant of many conditions as long as the site stays fairly cool in summer.
