Grape hyacinth (Muscari armeniacum) is a mid-spring blooming, perennial bulb in the Lily Family. It is not a true hyacinth (genus Hyacinthus). The common name comes from the resemblance of the clusters of the small, bell-shaped, cobalt-blue flowers to upside-down clusters of grapes. Grape hyacinth is hardy and with crocuses it blooms early in the spring.
