Bulbous cultivar of the Asparagaceae family, selected from Muscari armeniacum, native to the Caucasus and the Balkans. 'Blue Spike' is a double-flowered cultivar, obtained in cultivation and multiplied exclusively by vegetative means.
It reaches 15 cm in height. The leaves are linear, narrow, medium green, often appearing as early as autumn like the type species. What radically distinguishes this cultivar is the nature of its flower spikes: the flowers are fully double, abundant, in a medium lavender blue to blue-violet, with slightly paler shades than the species, and the spikes take on a dense, almost bushy appearance, more reminiscent of a small compact ball than a classic spike. This profusion of small doubled tepals gives each inflorescence a particularly full and textured character.
In cultivation under temperate climates, it generally blooms from April to May. Being sterile, it does not reseed, which can be an advantage where the type species tends to naturalize abundantly.
The growing conditions are identical to those of the species, well-drained soil, sunny to semi-shaded exposure, and it proves just as robust and without particular requirements once established.
