Scilla bifolia
Easy · Beginner friendlyAbout Alpine Squill
Two-Leaf Squill is a small southern European woodland bulb hardy in USDA zones 4-8, producing loose spikes of 6 to 12 star-shaped blue flowers on 4 to 6 inch stems in very early spring, often alongside snowdrops. Each bulb produces just two strap-like leaves, giving the species its name. A collector's bulb in American woodland and rock gardens, less common than Siberian squill but a welcome early-spring gem.

History
Scilla bifolia grows across much of Europe from France through the Balkans to the Caucasus in deciduous forests and mountain meadows. Linnaeus described it in Species Plantarum (1753); the name refers to the typical pair of strap-like leaves per bulb, which distinguish it from S. siberica. It has been grown in European gardens for at least five centuries; the Flemish herbalist Rembert Dodoens figured it in 1583.
Its clear sky-blue star-shaped flowers — sometimes white or pink — open just as tree canopy remains bare, making it ideal for ephemeral spring carpets under oaks and beeches. Variants include 'Alba' (white) and 'Rosea' (pink), grown since the 17th century. Contemporary designers including Piet Oudolf use it in drift plantings alongside snowdrops and crocus.
Native to southern Europe, Turkey, and the Caucasus, cultivated since the 1600s. Introduced to American horticulture in the 1800s as a specialty bulb. Remains a collector's favorite offered by specialty bulb merchants for its very early bloom time alongside snowdrops.
