MILKWEED

Milkweed owes its name to its milky sap, which contains toxic substances. However not all milkweeds secrete that sap, as we will see below. Also, insects that feed on milkweed have developed protections against those toxins.
The Latin name of this plant genus is ‘Asclepias’, from Greek ‘Asclepius’, the God of healing. This is because some species have medicinal properties.
We will examine three milkweed species below that grow in Eastern Canada – Swamp Milkweed, Butterfly Milkweed, and Common Milkweed, and compare their features. All photos by Denise Motard unless otherwise noted.
