Grape hyacinth (Muscari armeniacum 'Blue Spike') muss-KAR-ee ar-men-ee-AY-kum Genus:  Muscari These double-flowered grape hyacinths are a good candidate for beds and borders because they increase only by division. They also bloom longer than those that hasten through spring eager to set seed. April-flowering 'Blue Spike' has the largest inflorescence of the species, with fully double flax-blue fluffy heads (each pedicel carries multiple individual flowers instead of one) and narrow, linear leaves. Noteworthy Characteristics:  Good early color. Can be forced. Adaptable to various growing conditions, but must have well-drained soil. Care:  Likes fertile, moist but well-drained alkaline soil in full sun. Will take part shade. Plant 3 to 4 inches deep in groups or drifts in fall. Lift and divide when dormant in late summer or early fall. Propagation: 

 Divide when dormant; remove offsets in summer; sow seed in containers in a cold frame in fall.

Problems: 

 Generally problem free but prone to viruses.
