Daucus pusillus is a species of wild carrot known by the common names American wild carrot and rattle-snake-weed. Its Latin name means "little carrot", or "tiny carrot". It is similar in appearance to other species and subspecies of wild carrot, with umbels of white or pinkish flowers.
The taproots are small, edible carrots. This is a common plant found in the southern U.S. and along the west coast of North America from Baja California to British Columbia; as an example occurrence in Baja California, D. pusillus occurs in association with Mimulus aridus and Adiantum jordanii. It should not be confused with Conium maculatum, which is highly poisonous.
