Blue Spike Grape Hyacinth: Double Flax-Blue Heads for Longer Bloom

Muscari armeniacum 'Blue Spike' (Grape Hyacinth)

These double-flowered grape hyacinths increase only by division and bloom longer than seed-setting types. April-flowering 'Blue Spike' has the largest inflorescence of the species, with fully double flax-blue fluffy heads (each pedicel carries multiple individual flowers) and narrow, linear leaves.
