Any plant of the genus Hyacinthoides, in the family Hyacinthaceae, native to Eurasia. Bluebell, or wild hyacinth (H. nonscriptus or Endymion nonscriptus), and Spanish bluebell (H. 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.
