Muscari is a genus of perennial bulbous plants native to Eurasia that produce spikes of dense, most commonly blue, urn-shaped flowers resembling bunches of grapes in the spring. The common name for the genus is grape hyacinth.
Grape hyacinths are small spring-blooming bulbs, so named because of the tight little flower clusters that resemble grapes. Although the Muscari genus was previously categorized in the Liliaceae family (which also contains true hyacinths), it is now considered to be part of the Asparagaceae, or asparagus family. Regardless of plant taxonomy and who is related to what, grape hyacinths are little garden workhorses that can light up the early spring flower garden for years with little care. Grape hyacinths generally bloom in April or May, with blooms lasting for about three week.
