Asclepias syriaca
Common Milkweed is a wildlife-friendly perennial. The large, thick leaves are light green with red veins. Rounded clusters of fragrant, pinkish-purple flowers bloom June-August. Large, bumpy seed pods split open when ripe to release silky, wind-dispersed seeds. The seed pods are used in dried floral arrangements. This plant’s nectar is a food source for butterflies, native bees, bumblebees, and honeybees. Common Milkweed is an important nectar source and larval (caterpillar) host plant for Monarch (Danaus plexippus) butterflies. The leaves and stems have a milky sap, which contains cardiac glycosides. When ingested by Monarch butterfly larvae feeding on the leaves, the cardiac glycosides make them (and the adult butterflies) toxic to birds and other predators. Common Milkweed grows well in poor, dry soils. It spreads by self-seeding and rhizomes (underground stems) to form colonies. This plant is best used in wildlife gardens, meadows, and other naturalized areas.
