Asclepias incarnata or swamp milkweed, is a great perennial wildflower for full sun gardens in zones 3-9. While swamp milkweed can handle boggy soils, it can grow in regular garden soil with occasional watering. Growing to around three feet tall, it is a good plant for middle of a border.
The soft pink to mauve blooms are bee and butterfly magnets. Don't be alarmed if you see caterpillars munching the leaves as this is a host plant for the amazing Monarch butterflies!
Here are the steps for collecting the seeds from asclepias incarnata. The same seed collection method will work with asclepias tuberosa.
