Phenology | Flowering Jun–Aug(–Sep). | Flowering Apr–Jun. |
Habitat | Seeps and springs, damp rocks, vernal creek beds, cliffs, granite outcrops, rocky ridges, gravelly areas, meadow edges, stream edges. | Drained flats or slopes subject to vernal inundation, depressions in open fields, bare clay soils, vacant lots, roadsides. |
Elevation | (700–)1300–3500 m. ((2300–)4300–11500 ft.) | 10–800 m. (0–2600 ft.) |

Discussion | The distinction between Erythranthe latidens and E. inflatula sometimes seems arbitrary, perhaps because of gene exchange where they are sympatric in northwestern California. Erythranthe latidens in Oregon is known only from southern Harney County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
