Milkweed, “Irresistible Blend” Butterfly Flower Seeds
Butterflies and hummingbirds will flock to your garden to feast on the sweet nectar of this easy-to-grow, heirloom perennial. Often called swamp milkweed, this species grows best in moist or wet soils, such as near a pond or stream, but the loosely-clumped plants also grow well in a garden with regular watering. Decorative seed pods are beautiful in dried arrangements. Sap is toxic; avoid eye/skin contact and do not ingest. Individual flowers ½” long, borne in pink or white clusters.
150 mg seed packet.
