Bluebell, or wild hyacinth ( E. nonscriptus ), and Spanish bluebell ( E. hispanicus ), bearing clusters of bell-shaped blue flowers, are cultivated as garden ornamentals; some authorities place them in the related genus Scilla of the same family. Many other plants are commonly known as bluebells, including species of the genera Campanula , Eustoma , Polemonium , and Clematis . In the U.S. the name bluebell is usually reserved for Mertensia virginica .
