Plant of the Week: Canada Milk-Vetch
posted
Got milk? Our stormwater lands do! Canada Milk-Vetch (Astragalus canadensis) is a native perennial that you can find just about anywhere, just like our Wisconsin dairy cows. Although it sounds like quite the refreshing plant, it is not advised for humans or their cows to drink its sap as it contains toxins.
Canada Milk-Vetch is most recognized for its compound leaves and cream-colored blooms. The flower stalks contain over 75 individual tube-shaped flowers, creating a unique vertical bloom that attracts a variety of butterflies and bumblebees. Blooms can last up to three months long, ranging from May to August. Once established, the perennial can grow between 20 to 40 inches tall. This makes it a great option for sprawling hillsides needing erosion control.
Canada Milk-Vetch is quite similar to the beautiful, yet invasive, Crown Vetch, a pink and white flowering plant commonly seen along roadsides. Canada Milk-Vetch makes a great alternative for pollinators and people alike!
