Common Milkweed
Asclepias syriaca
 
A familiar and highly valuable native perennial with fragrant pink flower clusters and exceptional wildlife value. Common Milkweed is one of the most important plants for monarch caterpillars and supports a remarkable diversity of insects.
 
Its fragrant summer flowers attract numerous pollinators, while its large leaves provide food for monarch caterpillars. Common Milkweed can spread through underground rhizomes, making it best suited to naturalized areas, meadows, and larger native plantings.
 
Growing Conditions:
  • Sun: Full sun to part shade
  • Soil moisture: Dry–mesic to mesic
  • Soil: Adaptable; prefers average, well-drained soils
  • Height: 3–6 ft
  • Bloom time: Early–mid summer
  • Flower color: Pink to lavender
  • Native range: Eastern and central North America
 
Wildlife Value:
  • Critical host plant for monarch butterfly caterpillars
  • Excellent nectar source for butterflies, bees, and other pollinators
  • Supports a large diversity of native insects
 
Don't Worry If It Doesn't Flower Right Away:
Native perennials don't always flower their first year, and that's completely normal! Young plants often put much of their energy into developing a strong root system and establishing themselves in their new environment. Depending on the species, you may see limited or no flowering during the first growing season, with more substantial flowering beginning in year two and beyond.
 
Watering for Establishment:
For the best results, water your new plants regularly during their first 6 weeks after planting, particularly during periods of hot or dry weather. Once established, many native plants are relatively drought tolerant when planted in an appropriate location for the species.
 
Plant for the future: The first year is about putting down roots. Give your native plants time to establish, and you'll be rewarded with stronger, more resilient plants in the seasons ahead.
 
Garden Use:
Great for meadows, naturalized areas, pollinator gardens, and larger native plantings. Because Common Milkweed can spread, it is generally better suited to areas where it has room to establish rather than small formal beds.
 
WNS Note:
Asclepias syriaca is a straight native species, not a cultivar, selected for its exceptional ecological value and importance to monarchs and other native wildlife.
