The anemone genus comprises 200 or more flower species. They all belong to the ranunculus or Ranunculaceae family. Wild anemones grow throughout most parts of the Northern Hemisphere. As a genus, anemones are prevalent throughout much of the world, including Asia, Europe, Japan, and North America. The fact that native habitats are spread out throughout a large part of the globe complicates botanists’ efforts to find their exact origin.
