Prospero minimum is an autumnal flowering plant of the family Asparagaceae, subfamily Scilloideae that is endemic to Crete, Greece. It is a diploid species in the Prospero autumnale cryptic species complex. This tiny autumn-flowering plant is among the smallest members of the squill family, with thread-like leaves less than 1 mm wide and delicate pink star-shaped flowers. It grows on limestone rubble near Imbros Gorge and was recognized as a distinct species in 2000 when scientists documented its uniquely diminutive size compared to related plants.
