Summary

Prospero autumnale, commonly known as Autumn Squill, is a deciduous perennial bulb that is native to a variety of habitats including rocky slopes, open woodlands, and grasslands in the Mediterranean Region. It is a small plant, typically growing to a height of 0.2-0.5 feet (0.06-0.15 meters) and spreading 0.2-0.3 feet (0.06-0.09 meters) wide. The Autumn Squill has a delicate appearance, with slender stems and narrow leaves. It produces small, bell-shaped purple flowers in late summer to fall, which are moderately showy and add a splash of color to the landscape.

Autumn Squill is valued for its ability to naturalize and provide late-season blooms. It is often used in rock gardens, borders, and as underplanting for larger shrubs or trees. This bulbous plant is relatively low maintenance, requiring only moderate watering once established and thriving in well-drained soils. It prefers full sun to part shade, which allows for greater flexibility in garden design. While generally disease-free, it can be susceptible to bulb rot if planted in overly wet conditions. Autumn Squill is not known for aggressive roots or significant pest problems, making it a reliable choice for many garden settings.CC BY-SA 4.0
