How to tell it
A compact ovoid head two to three centimetres across, with dozens of tightly packed dark purple or reddish pink flowers. No bulbils among the flowers, unlike several other wild alliums. Cylindrical hollow leaves, mostly already dry at flowering. A strong garlic smell when any part is crushed.
What it is confused with
Grape hyacinth
Muscari neglectum
Leaves and bulb are alike and grow side by side. The allium smells of garlic, the grape hyacinth smells of nothing and is toxic. And the hyacinth's flowers are closed beads with a white mouth, the allium's are open and starry.
Open sheet →What it is for
Bulb and leaves were traditionally used as seasoning, weaker than garden garlic. The garlic smell guarantees the genus, but does not replace certainty: there are toxic bulbs with similar scentless leaves, and it is the smell that decides, not the look.
Traditionally used as food. This is not permission to eat it.
