Scilla bifolia L. is commonly cultivated, spreads readily in gardens, and probably will be found as an escape at some point. It is a deep blue-flowered (though pink and white forms exist), small species with a raceme of up facing flowers (like S. forbesii), but much smaller and lacking both a pale center and basally fused tepals.
1. Flowers spreading to nodding, bell shaped; tepals separate.
1. Flowers up facing, opening ± flat; tepals fused for ca. 3–4 mm at the base.
2. Flowers 1–2 (–3), pale blue (rarely white) throughout.
2. Flowers mostly 3–8 in a raceme, deep blue with a distinctly paler, almost white, center.
