Good early spring bulb for naturalizing.  I have several small, but spreading, colonies.  I watch for the ripe seed cases when the foliage starts to die back and scatter the seeds around.  This is a non-invasive species that quickly disappears by the end of May and do not compete with other plants. From seed to flowering size bulb normally takes 3 years,

Grow 6" high in full to partial sun.  Hardy to zone 3, and 2 with protection.
