Over the Years - Common Milkweed smells amazing, pollinators adore it, and Monarch butterfly caterpillars require it. However, chose your spot carefully as this milkweed can quickly over run small spaces. We designated a back section of our yard specifically for Common milkweed. It politely shares a space with the likes of: Ironweed, Joe-pye, Giant Sunflowers, Some of the shorter native plants like Bergamt and Yellow Coneflower have to work a little harder for resources
Host Plant - Butterflies need two types of plants in order to survive; the first are the nectar plants like Joe- Pye Weed ones with a flat "landing pad" that allow the adult butterfly to easily rest and take a nice long drink. Like most living things, the diet of the young differs from that of the adult. This is the case with butterflies; after working their way out from the safety of their chrysalises (cocoon) they are hungry. Dinner needs to be there right on the spot. The young of the Monarch butterflies and eleven other species of Lepidoptera (butterflies) first meal needs to revolve around milkweed plants.
When planning a butterfly garden, be certain to plan for the adults as well as their larvae. Although butterfly bushes (Buddleja species) are beautiful and do provide nectar for adults, there are no species of butterflies in North America that use this plant as a larval host plant.

Propagation Notes Swamp Milkweed
Stratifying Seeds
1. Zip lock plastic bag2. Few tablespoons of Vermiculite3. Dampen vermiculite - not soggy4. Store in refrigerator for 30 days before sowing
Seeds require cold, moist storage in order to germinate
Wind Dispersed - Or let nature do the work and allow the wind to spread seed. However, if you have a small yard this may not be the best life choice, that is unless you aren’t particular where Common Milkweed decides to sprout. Asclepias tuberosa, Asclepias incarnata are alternative native milkweeds that aren’t quite as prolific. Check their ideal growing conditions to see if your yard is suitable. Another option would be to rubber band Common Milkweed pods closed in the fall before they mature and fly all over the neighborhood.
