Details from Andy’s Northern Ontario Wildflowers
Flower: Lavender; star-shaped individual flowers; dense clusters located at top of plant where leaves join the stem; drooping, June to August.
Leaves: Opposite, blunt; coated with grayish down on the underside.
Stem: Erect, have milky sap.
Fruit: rough-textured pod; splits open to release silky sails attached to seeds.
Height: 1-2 m.
Habitat: Meadows, fields, rocky flat areas, and roadsides.
General Interest: The seed pods look like a large cocoon and seeds are carried on silky fluff. This plant is a favourite to the Monarch butterfly. The plant juices impart a bad taste to the mature butterflies, which serves to protect the butterflies from birds. Candle wick made of the milkweed silk burns cleaner than wick made of cotton. Milkweed contains compounds that are toxic to animals.
