Siberian Squill is an uncommon plant that occurs in only a few counties in Illinois, primarily in the east-central region of the state. It was introduced into the United States from Eurasia as a horticultural plant because of its attractive flowers. Habitats include disturbed grassy areas, areas along railroads, flower gardens, and deciduous woodlands. While it may occur in sunny sites, this is primarily a spring-blooming plant of deciduous woodlands. The small dormant bulbs have the capacity to survive major earth-moving operations, and may reestablish themselves wherever the soil is dumped. Siberian Squill is more robust and more likely to naturalize than many other spring-blooming flowers from bulbs, but it is not particularly aggressive. At a favorable site, a few plants may form a sizeable colony after several decades.
