Large-flowered fiddleneck is a rare (CNPS 1B.1) California native annual found in the western San Joaquin Valley, specifically in San Joaquin County, on grassy slopes at elevations below 300 meters. Flowering from March to May, this plant produces striking red-orange flowers 14 to 20 millimeters long with a distinctive corolla limb 10 to 15 millimeters in diameter. Growing with delicate stems, it develops linear to narrow-ovate leaves that are characteristic of its fiddleneck genus.

The fruit is small, approximately 3 to 4 millimeters long, with a smooth, shiny brown surface marked by three longitudinal ridges.
