Androstephium coeruleum, commonly called blue funnel-lily, is a herbaceous perennial growing from corms.

It has light blue to violet purple flowers and grows up to 35 cm tall.

It is found growing in prairies and on grassy slopes in its native range within Texas, Oklahoma and Kansas of the United States.

There is great variability in the shape and color (sky blue to purple to white) of flowers of the species; they have a faint sweet scent described as "grape-like".

Fruit set is infrequent - whether due to loss of native pollinators or self-sterility is unknown - and ripens by late April, when it splits open, presenting the thin, flat black seeds to the wind.
