Wild Onion - also known as Crow Garlic - grows to a height of 60cm. It bears small 2-4mm across flowers which are pink or green-white, wide bell-shaped, have protruding stamens and are on 1-2cm long stalks arising from round clusters of bulbils. These clusters are protected by a papery bract initially. The bulbils detach, falling to the ground and becoming new plants. The clusters are borne on round, stiff, smooth, often blotched stems. Leaves are grey-green, narrow, half-cylindrical and hollow. Crow Garlic prefers dry grassland, disturbed ground and hedgerows. It is a native perennial, occasional in East, South East and South West. It belongs to the Daffodil or Amaryllidaceae family.
I found and photographed Crow Garlic on the North Bull Island, Co Dublin and around Killiney Bay, also in Co Dublin, in 2012.
