Fool's parsley is native to Europe, western Asia and northwest Africa but has been introduced elsewhere (Wikipedia 2012).
This is a poisonous species.
There is a historical report of this species for BC in the Illustrated Flora of British Columbia, which says it was "reported by Scoggan". However, no additional information is available; no specimen at CAN.
