They are extremely attractive to spring-flying pollinators, particularly the hairy footed flower bee, Anthophora plumipes. Grape hyacinths (Muscari) look much like little miniature hyacinths. These plants are smaller and only get about 6 to 8 inches (15-20 cm.) high. Each grape hyacinth flower looks like it has little beads all strung together up and down the stem of the plant.
