cow parsnip

Heracleum maximum

Summary ⁵

Heracleum maximum, Cow Parsnip (also known as Indian Celery or Pushki) is the only member of the genus Heracleum native to North America. Its classification has caused some difficulty, with recent authoritative sources referring to it variously as Heracleum maximum or Heracleum lanatum , as H. linatum, or as either a subspecies, H. sphondylium subsp. montanum, or a variety, H. sphondylium var. linatum, of the Common Hogweed (H. sphondylium). The classification given here follows ITIS.

Distribution ⁶

Cow parsnip occurs from Newfoundland west to Alaska and south to
California, Arizona, New Mexico, Kansas, Missouri, and Georgia
[22,26,30,47,68]. It is not found in northern Canada or in the extreme
southern and southeastern regions of the United States.
