Siberian Squill is a lesser-known invasive plant that emerges early in the spring and blooms very early as well (April-May). It has tiny blue, bell-like flowers (1-inch-wide) and can tolerate cold as well as shade, making it a popular landscape plant. However, it quickly takes over landscapes and native woodlands as a groundcover, replacing native groundcover species. It is also highly toxic to humans and animals, including pets if ingested.
Siberian squill has upright, 5-inch grass or iris like leaves. Flower stalks have one to three bright blue glowers with 6 petals. Some varieties also come in colors such as white, pink, or violet.
Control methods for Siberian Squill:
- Small populations can be easily dug out when the ground is moist.
- Removal should focus on plants that have not yet flowered.
- Mow after bloom to prevent spreading by seed.
For large populations, herbicide control may be necessary.
