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).
Silybum Silybum (milk thistle) is a genus of two species of thistles in the (daisy family). The plants are native to the Mediterranean regions of Europe, North Africa, and the Middle East. One species has been introduced elsewhere, including in North America. The name "milk thistle" derives from a feature of the leaves, which are prominently banded with splashes of white. Historically, these milky bands were said to be Mother Mary's milk, and this is the origin of another common name, St. Mary's thistle. The most widespread species is "Silybum marianum".
