About

Prospero autumnale, the autumn squill, an autumnal flowering plant of the family Asparagaceae, subfamily Scilloideae, is found in the Mediterranean region from Portugal and Morocco east to Turkey and the Caucasus, plus Great Britain. Despite being classified as a single species, it is actually a cryptic species complex, with a variety of cytotypes having been discovered which are phenotypically indistinguishable from each other.
