About
Scilla greilhuberi, Greilhuber's squill, is a bulbous perennial with mid-green, strap-shaped leaves 15�20 cm long that emerge in autumn and persist to spring when the violet-blue flowers with reflexed petals appear. A rewarding and ornamental autumn-foliage, spring-flowering bulb for a sunny, well-drained border.
