Save a Monarch

Plant a Milkweed, Save a Monarch

The noxious weed list, Regulation 1096 of the Weed Control Act, has been updated. Dogstrangling vine and black dog-strangling vine, have been added to the noxious weed list, while all milkweed species have been removed. These changes are effective immediately.

Common milkweed is toxic to grazing livestock and at one time was considered to be a threat to activities on agricultural and horticultural land. Today, however, rural landowners have a number of options to control common milkweed. Other plants in the milkweed family are not generally known to be threats to agriculture. In fact, the four-leaved milkweed is a "species at risk" under the Endangered Species Act, 2007.

Recent evidence has shown that the eastern North American monarch butterfly population is in serious decline. Milkweed species, especially the plant known as common milkweed, are an important food source for the larvae of the monarch butterfly. The leaves of the plant also serve as a place to lay eggs.

Gardeners and concerned citizens are encouraged to be responsible when using native milkweed plants to provide a habitat for monarch butterflies. Some varieties of milkweed-such as swamp milkweed-are less likely to spread and interfere with agriculture and are preferred over common milkweed. Planting common milkweed next to a farmer's fields is not recommended.
