Monarch butterflies lay their eggs on milkweeds which is the only plant the larva eat. Toxic glycosides from the plant make the adult butterflies poisonous to birds and other predators.

Historical Lore: Despite it's toxicity the very young shoots and leaves and the newly formed seedpods can be eaten if boiled in two or three waters discarding these to remove the toxins and bitterness before cooking. The young shoots are sometimes referred to as Wild Asparagus. There are accounts of sugar being made by pressing fresh flowers and cooking down the juice.

The silky down of the seeds has been used to fill bedding and life jackets and was once thought to have a future as a commercial fiber. The fiber from the stems was also used much like Indian Hemp, Apocynum cannabinum.

Medical Uses: The down of the seed has been used to dress wounds and the latex like sap applied to various skin eruptions. There are several accounts of the root along with the root of Jack in the Pulpit, Arisaema triphyllum being used by Native American women to prevent conception. A root tea has been used by various tribes as a diuretic, expectarant and for any number of medical conditions including respiratory conditions, joint pain and digestive problems. Warning:This plant, especially the root is considered toxic!

By: Newcomb, Lawrence and Illustrated by Morrison, Gordon. 1977, Little, Brown and Company, ISBN:0-316-60442-9

One of the best general guides to wildflowers of the North Eastern and North Central United States. Newcomb's key is an excellent, simple method for identifying plants. Newcomb has drawings for almost every plant mentioned that are excellent aids to identifying the species. Though only the more common plants are covered this is often the first book I pick up when trying to identify a wildflower.
