Facts About

Siberian squill originates from Russia, Turkey and the Caucasus, and is widely cultivated for its dark blue, bell-shaped flowers. It can be quite invasive in northeastern North America, although it has so far been uncommon in New England, where it has been collected only in Massachusetts.

Habitat

Anthropogenic (man-made or disturbed habitats), meadows and fields
