Clusters of bell-shaped inverted tulips decorate mountainous areas of Kuhrang, western Chaharmahal-Bakhtiari province, now that spring is in full swing.

The flower, also known as the crown imperial tulip, has red, yellow or orange blooms often with a crown on top, hence the name, and have been adding a colorful touch to the local landscape.
