Scilla bifolia, the alpine squill [1] or two-leaf squill, is a herbaceous perennial plant growing from an underground bulb, [2] belonging to the genus Scilla of the family Asparagaceae.

Contents

The Latin specific epithet bifolia means "twin leaved". [3]

Description

Scilla bifolia grows from a bulb 1–2 cm (0.4–0.8 in) across. [2] There are two or rarely three lance-shaped, curved, fleshy and shiny leaves [2] and the bases of the leaves clasp up to about the half of the stem (amplexicaul). [2]

The flowering stems are erect and unbranched, 10–20 cm (4–8 in) high. [2] The raceme bears 6-10 flowers, each 1 cm (0.4 in) across. [2]

The flowers of Scilla bifolia are upward-facing, unlike the nodding flowers of Scilla siberica (Siberian squill). They bloom from early to late spring. The six tepals are deep violet-blue, more rarely white, pink, or purple. [2] The fruit is a capsule 6–8 mm (0.2–0.3 in) across. [2]

S. bifolia has gained the Royal Horticultural Society's Award of Garden Merit. [4] [5]
