Cow Parsnip NOT Giant Hogweed!

The Church Ranches common lands are filled with countless native plants and wildflowers. One of these is Cow Parsnip, which might be mistaken for Giant Hogweed. Both plants are members of the carrot family and are found in similar habitats and have a similar appearance. However, Cow Parsnip is native to Alberta and while its sap might cause some skin irritation to sensitive individuals, it does not have the same toxicity as Giant Hogweed. The overall size of the plants are different. As well, the leaves and stems have distinctive characteristics. A Cow Parsnip leaf look similar to a maple leaf. Its stem has deep ridges and fuzzy hairs and has very few purple marks. The Giant Hogweed leaf has "lobed leaves" with deep incisions. The stem has many purple spots and stiff bristles. To date, no Giant Hogweed has been reported in the Province of Alberta.
