USDA Native Status: L48 (N)

A dandelion-like rosette of jagged-edged leaves and bright yellow flowers with 4 broad petals.

This is representative of several low, yellow-flowered evening primroses without stems. The root of this plant branches beneath the ground, and the plants form patches on the surface. It was previously placed in the big genus Oenothera, but the knob at the end of the style indicates it belongs in Camissonia.
