Cow Parsnip is a very, very big bog species. It can grow to 5 feet or more in height and 4 to 5 feet wide. Its large umbels of pure white flowers are long-lasting and, if properly placed in a large bog garden, this species can be a very attractive, eye-catching foundation plant. It can tolerate full sun to shade as long as the soil remains moist and humusy.
