Common milkweed, Asclepias syriaca

Asclepias syriaca, commonly known as common milkweed, is a native North American plant known for its ecological importance, especially to pollinators like monarch butterflies.

🌸 Key Features

  • Family: Apocynaceae (formerly Asclepiadaceae)
  • Height: 3–5 ft (0.9–1.5 m), sometimes taller
  • Leaves: Broad, opposite, and oval with a smooth margin
  • Flowers: Pink to purplish, fragrant, blooming in spherical clusters (umbels)
  • Fruit: Long, spiny seed pods that split open to release silky-haired seeds
  • Latex: Milky sap that is mildly toxic and a deterrent to herbivores

    🐝 Ecological Importance

  • Host plant for monarch butterfly (Danaus plexippus) larvae
  • Nectar source for bees, wasps, beetles, and other butterflies
  • Seeds dispersed by wind thanks to silky tufts (coma)

    🌱 Growing and Care

  • Hardiness Zones: 3–9 (USDA)
  • Light: Full sun
  • Soil: Well-drained; tolerates dry to medium conditions
  • Spread: Can spread aggressively by rhizomes; suitable for wild gardens or meadows

    🧪 Uses

  • Traditional uses: Native American groups used parts of the plant medicinally and for food (young shoots, buds, and immature pods – only after proper preparation to reduce toxicity).
  • Modern uses: Fiber from stems has been used as cordage; floss used as insulation or stuffing.
