Safran
The domesticated saffron crocus, "Crocus sativus", is an autumn-flowering perennial plant unknown in the wild. It probably descends from the eastern Mediterranean autumn-flowering "Crocus cartwrightianus" which is also known as "wild saffron" and originated in Crete or Central Asia. "C. thomasii" and "C. pallasii" are other possible sources. As a genetically monomorphic clone, it slowly propagated throughout much of Eurasia.
