(=Sibbaldiopsis tridentata ‘Nuuk') This species of Cinquefoil grows wild over most of the Northern Hemisphere, including the high Arctic. ‘Nuuk’ was selected in Greenland and named for its capital city, so it shines so far as cold-winter tolerance. If forms a low mat of shiny evergreen leaves, bearing small white flowers in late spring and early summer that resemble little buttercups. An excellent filler plant for the rock garden or border edge, also good as a groundcover. Foliage turns wine and bronze shades in the colder months. Drought tolerant once established. Easily divided in spring or early fall.
