First, they are called 'Fall Bulbs' because they are planted in the fall. They bloom in spring, some in very early spring. Grape Hyacinth (Muscari), for example, can bloom when snow is on the ground and are sometimes planted in lawns because they are finished blooming long before the turf comes out of dormancy. Fall bulbs can add badly needed color to an otherwise bleak landscape and bring the hope of spring and all its glory.
