Stipa cernua (Nodding needle grass) is a native California grass in the Poaceae family, recognized by inflorescence openness and size.

Nodding needle grass is a native perennial found in northern Coast Ranges, California Floristic Region, northern Sierra Nevada Foothills, Tehachapi, Great Valley, San Francisco Bay Area, southern Coast Ranges, and southwestern California in grasslands, chaparral, and juniper woodland at elevations of 5 to 1,700 meters. Flowering from February to July, this grass produces delicate, nodding pale green to tan flower heads with distinctive long, twisted awns. Growing 30 to 100 centimeters tall with slender stems between 1 to 3 millimeters in diameter, it forms loose, open clusters of fine, thread-like stems. Its narrow leaves are 3 to 26 centimeters long and less than 1.2 millimeters wide, typically flat or slightly rolled. The plant's most distinctive feature is its remarkably long, bent awn measuring 50 to 106 millimeters, which twists and waves gracefully in the wind.
