Fritillaria flower which comes in red, yellow, and sometimes orange spreads over Iran’s lands after winter and makes the lands beautiful at springs. Its life span is short and flowers at the end of Farvardin (April) and cease flowering at early Ordibehesht (May) as rain falls begin. Fritillaria has an ancient trace in Iran. In one of the Iranian old stories named “Siavash”, this flower becomes upside down in order to grieve on the heroes innocence and never stands up again. Therefore, because of this story, it is also called the tears of Siavash. People from antiquity believed that its upside down position and frost falling down is because of this catastrophe.
