Cow Parsnip is one of the
largest members of the Parsley Family in Colorado, with plants growing to over
6 feet tall. Cow Parsnip grows on streambanks and moist areas in the foothills
to mountains. Leaves are large, ternately compound (3 leaflets) with palmately
lobed leaflets and toothed margins. A large umbel of white flowers appears at
the top of the stem. The size of the plants and the broad leaves help
to identify this species.
