Scilla bifolia, commonly called scilla, two-leaf squill or alpine squill, is a perennial of the asparagus family. It is native to lower mountain areas from central and southern Europe, and south to Turkey and Syria.
The two-leaf squill grows from a bulb and has two lance-shaped, curved, fleshy and shiny leaves. The bases of the leaves clasp up to about the half of the stem.
The flowering stems are 10–20 cm high. The flowers are upward-facing and bloom from early to late spring. The six tepals are deep violet-blue, more rarely white, pink, or purple. The fruit is a capsule 6–8 mm across.
