Landscape Attributes

Blue Squill is an herbaceous perennial with tall flower stalks held atop a low mound of foliage. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

This is a relatively low maintenance plant, and should be cut back in late fall in preparation for winter. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.

Blue Squill is recommended for the following landscape applications;

  • General Garden Use
  • Naturalizing And Woodland Gardens

Planting & Growing

Blue Squill will grow to be about 12 inches tall at maturity extending to 30 inches tall with the flowers, with a spread of 12 inches. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 5 years. As this plant tends to go dormant in summer, it is best interplanted with late-season bloomers to hide the dying foliage.

This plant does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This species is not originally from North America, and parts of it are known to be toxic to humans and animals, so care should be exercised in planting it around children and pets. It can be propagated by multiplication of the underground bulbs.
