Wild carrot

A closer look.

UC IPM describes a rosette stage followed by bristly flowering stems, with flowers generally appearing from May through September. Wild carrot occupies roadsides, fields, and other disturbed ground and can cross with cultivated carrot. Hairiness varies with plant part and growth stage; no single feature establishes safety.

Through the seasons

UC IPM gives May through September as the flowering period. Spring, summer, and autumn inclusion reflects that broad interval; local conditions vary.

Knowledge has a context.

No reviewed historical-use account is included. Cultivated carrot and wild plants should not be treated as interchangeable in identification or use.

A record of where it was found.

UC IPM reports wild carrot across much of California apart from the Great Basin and deserts, especially in northern and coastal areas. Specimen dots show a selected historical record subset, not continuous occupancy.

What this map includes

From the first 256 results returned by the stored GBIF query, 20 specimens met the coordinate and reuse filters; 236 were excluded. The query matched 256 records at retrieval. This subset is not random or exhaustive.

Records are labeled California, have coordinates, and lack GBIF geospatial-issue flags. We exclude known coordinate uncertainty above 25 km and use only CC0 or CC BY 4.0 records. 16 included records do not report coordinate uncertainty. A 0.25° cell is about 28 km north to south; it does not show an exact collecting site.

Matched taxon: Daucus carota ↗.
