Colchicum asteranthum Vassil. & K.M. Perss.
Colchicum asteranthum was discovered relatively recently in 1999, and was described three years later. So far, it has been found only on Lerkio of Peloponnesus, where its distribution is limited to slopes with southwest to southeastern exposure. This very limited distribution makes Colchicum asteranthum one of the rarest species of the genus Colchicum in Greece.
It prefers areas of the mountain with terra rossa and without extensive tree cover, at an altitude of 950 to 1450 m. Its white or pink flowers open in the winter, during December and January, leaving a honey perfume.
The plant’s winter flowering poses the risk of reduced sexual reproduction due to the possible bad weather and the resulting lack of pollinators. However, there is the possibility of vegetative reproduction through roots that compensates for the losses. It has been estimated that there are several thousands of individuals on the mountain, but they appear in an area of very limited size. For this reason, C. asteranthum is included in the Red Data Book of Rare and Threatened Plants of Greece (2009), characterised as "Vulnerable".
