Scilla siberica

Despite its name, Scilla siberica is native to the Caucasus, southern Russia and western Siberia. A small bulbous plant with a tunicated bulb, it forms a tuft of 2 to 4 fleshy, lanceolate leaves. It flowers very early in spring, from February to March, producing several short 10–15 cm stems each bearing a few nodding, bell-shaped flowers of a characteristic deep blue, occasionally white in some cultivars. It self-seeds and naturalises readily in cool spots. It needs soil that is well drained yet cool and humus-rich, a sunny to part-shaded position under deciduous cover, and dry summer dormancy.
