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.
