Lilium parvum

Lilium parvum is a species of lily known by the common names Sierra tiger lily and alpine lily. It is native to the Sierra Nevada of California and Nevada. The plant grows in mountainous forests, sending up stems with flower clusters of lily flowers during the summer months. The flowers are small for lilies, and more bell-shaped than most others. They are yellowish-orange to dark orange-red with lighter orange or yellow centers. The petals are spotted with purple or brown markings. There is a variety that bears lighter pink flowers in the foothills of El Dorado County, California, which is known by the informal common name ditch lily. The plant also readily hybridizes with other Lilium species growing close by.
