The Potentilla verna nana that grows in Anchorage is a very low dense mat, not a big spreader in my rock garden, small attractive leaves and many yellow flowers. Sorry, not sure of its relationship to grandiflora and never heard it mentioned among knowledgable plant friends. Let the lumpers and splitters fight it out whilst it thrives and blooms unaware of such issues.
