Squill have narrow leaves and most flower in the spring. Flowers are usually blue, but white and pink species also exist. The plants are best grown in large, bold plantings in light shade. They will grow in almost any kind of soil as long as it is moist in spring. Set the bulbs 3-4 inches deep and 6-8 inches apart. They need not be lifted or divided unless you intend to propagate.
Siberian Squill is a popular spring-flowering variety, and especially the cultivar "Spring Beauty." These bulbs will often produce more than one 8-inch flowering stem, with up to six brilliant blue flowers on each. Leaves are bright green and 8 inches in length. It's ideal for planting among shrubbery and for naturalizing. A white form is sometimes found.
