Description

edit

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]
