Siberian squill (Scilla siberica) is a popular landscape plant that can be invasive.
- Siberian squill is found in native woodlands.
- It readily spreads itself and is hardy and cold tolerant.
- It is not on any Minnesota control list, but may be added in the future.
How to identify Siberian squill
- Small, 4–8 inches tall, early flowering bulbous perennial.
- It grows, flowers and then goes dormant at the same time as many native spring ephemerals, plants that emerge and bloom right after the snow melts.
- One or more arching, hairless flower stalks form from the center of a rosette.
- 5-inch-long, grass-like, hairless leaves emerge from one point.
- 1-inch-wide, bell-shaped flowers occur singly or as a group of 2–3 at the top of a slim stem.
- Six flaring, blue petals with a dark blue center strip and six white stamens with blue tips.
- Flower color may vary with variety and include white, pink or violet.
- Seed capsules are green and bumpy.
- They turn brown as they mature and split to produce dark reddish-brown seeds.
