This member of the Apiaceae family was described by Carl Linnaeus in 1753. It is found in most of Europe and has been introduced to North America. It grows in rich or well-drained soil with some water and some to a lots of sun. The tap-root will get three centimetres in diameter, the whole plant can reach for 2,5 meters. The flowers are white, and beside from seeds, it can be reproduced by dividing the roots, which forms off-shoots.
The genera name references the Greek koneios; 'spin' or 'whirl', alluding to the dizzying effects of the plant's poison after ingestion. The species name means 'spotted, stained or blotched'.
