Are Leontopodium and Sandersonia both native to Europe?
Leontopodium Leontopodium is a genus of plants in the Asteraceae family (which also includes daisies and sunflowers). The genus is native to Europe and Asia. The fuzzy and somewhat stocky "petals" (technically, bracts) could be thought of as somewhat resembling lions' paws —hence the genus name combining "léōn" (lion) and "pódion" (foot).
Solidago latissimifolia Solidago latissimifolia, common name Elliott's goldenrod, is North American species of flowering plants in the sunflower family. It is native to the Atlantic Coast of the United States and Canada, from Nova Scotia south to Alabama and Florida.
