Some people think that bluebells and grape hyacinths are identical, but they are not. They both share a similar blue color, but there, the similarity ends. Blue bells are indeed bell-shaped, just as the florets of grape hyacinths are. But the petals open up and curl back around the edges. They do not do this on grape hyacinths. Like grape hyacinths, bluebells do belong to the asparagus family, but the genus name is Hyacinthoides.
