Introductions of Rosa lucieae in North America are largely from cultivars. The species is most common in southern and mid-latitudes of eastern and south-central United States. With spreading stems to 60 dm, R. lucieae is a typical stoloniferous plant forming carpets of colorful groundcover.

Rosa lucieae cultivars and hybrids have been widely used in breeding rambler and climbing roses. Its creeping stems extend to 60 dm and root readily, forming a white- or pink-petaled ground cover for gardens and cemeteries, and along highways where it also serves to stabilize verges. The most commonly found cultivar in North America is 'Dorothy Perkins'.
