The flowering plant genus Ipheion (starflower) belongs to Allioideae subfamily of the Amaryllidaceae family. There has been uncertainty as to the limits of the genus; research published in 2010 suggests that although related to genera such as Tristagma and Nothoscordum, it is a distinct genus of 3 species. However, other sources do not recognize the genus, placing all the Ipheion species in Tristagma.
They are small bulbous perennials with narrow grass-like leaves and honey-scented star-shaped flowers in spring, usually in shades of white or pale blue. The genus occurs naturally in Argentina, Uruguay, and southern Brazil, although Ipheion uniflorum has naturalized elsewhere.
