Found on free-draining soils, native or long-naturalised in grasslands, hedgerows, pine plantations and rough ground, and on roadsides on a wide range of nutrient-poor soils. It very occasionally occurs as a short-lived garden escape or outcast near habitation, on roadsides, allotments and waste ground although most garden escapes are of the garden variety Muscari armeniacum.

Flowers March to May.

Perennial bulbous plant.

Most common in East Anglia and Oxfordshire but declining even in these areas.

Rare in Leicestershire and Rutland. In the 1979 Flora survey of Leicestershire it was found in 1 of the 617 tetrads.
