Asclepias incarnata Swamp Milkweed
Swamp Milkweed is a particularly gorgeous wildflower. Clusters of pink and white star flowers grow on 4' tall stems with long, willowy silver leaves. Each cluster is 4" across and is and irresistible to Monarch butterflies who lay their eggs on the stems and leaves. This is THE native host for our western Monarch butterfly.
Asclepias incarnata looks fancy, but it's tough and vigorous. It thrives in swampy spots and doesn't mind wet feet. Plant it in sun or part shade and keep it watered. It's perennial in all zones 3-9 and does very nicely in a large pot.
Germination can be slow, but these seeds were just harvested and should pop up quickly.
