Asclepias syriaca
Observe the monarch butterfly lifecycle right in your garden! This heirloom species provides food and habitat for monarch butterflies and is an essential host plant for their caterpillars. In summer, pink to purplish or white flowers are followed by decorative seedpods that are beautiful in dried arrangements. Robust, shrub-like perennial spreads by underground rhizomes. Native throughout much of the eastern and central United States. Sap is toxic; avoid eye/skin contact and do not ingest.
