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).
Chrysosplenium iowense Chrysosplenium iowense is a species of flowering plant in the saxifrage family known by the common name Iowa golden-saxifrage. It is native to North America, where it is "primarily a Canadian species", occurring from the northern Northwest Territories south to British Columbia and east to Manitoba. There are also disjunct, relictual occurrences within the United States, in the Driftless Area of Minnesota and Iowa.
