Sowing: In late fall, plant the swamp milkweed seeds just beneath the surface. They'll start to germinate in spring, after the last frost. Once the seedlings pop up, thin them out to keep only the strongest one; they usually don't handle being transplanted well because they dislike having their roots disturbed. If you're planting in spring, mix the seeds with some moist sand and chill them in the fridge for 30 days before sowing them directly.
Growing: This plant doesn't do well in dry conditions, so you might need to water it to keep the soil nice and moist. The flowers are great for attracting bees and butterflies, but they also keep deer away. To help this plant thrive, make sure to keep competing weeds at bay.
Harvesting: This plant makes for a beautiful cut flower. When you cut the stems, go for long ones and pick flowers that have just opened up. Just a heads up, the milky sap can be mildly toxic and might irritate your skin.
Seed Saving: After the flowering is done, you'll see 3-4" narrow pods forming. Make sure to pick the pods before they burst open and let the silky fluff carry the seeds away. Once the seeds inside turn a mature brown color, take the pods off and lay them out to dry. Open the pods and remove the silky seed material, then get rid of the fluff from the seeds. Store the seeds in a cool, dry spot.
