Swamp Milkweed
Swamp Milkweed (Asclepias incarnata) is a hardy, moisture-loving perennial known for its vibrant clusters of pink, mauve, or white flowers that attract a wide range of pollinators, including monarch butterflies. Thriving in USDA Hardiness Zones 3-8, this native North American plant grows 3-5 feet tall and spreads about 2-3 feet wide, making it a stunning addition to rain gardens, wetland areas, and naturalized landscapes. Swamp Milkweed is particularly valued for its role in supporting monarch butterfly populations, as it provides essential nectar and serves as a host plant for monarch caterpillars.
Perfect for planting in areas with consistently moist to wet soils, Swamp Milkweed excels in rain gardens, pond edges, or low-lying areas where water tends to collect. While it prefers moist conditions, this adaptable perennial can also tolerate drier soils once established, making it a versatile choice for a variety of landscapes. In mid-to-late summer, its fragrant blooms attract bees, butterflies, and other beneficial insects, turning your garden into a hub of pollinator activity. The plant’s narrow, lance-shaped leaves add texture to garden beds, and the upright stems provide height and structure.
In addition to its ecological benefits, Swamp Milkweed is low-maintenance and easy to grow. Plant it in full sun to partial shade, and it will thrive with minimal care. This deer-resistant perennial not only adds beauty and biodiversity to your garden but also plays a critical role in supporting native wildlife. Whether used in pollinator gardens, rain gardens, or as part of a naturalized planting, Swamp Milkweed delivers long-lasting color and environmental benefits to any outdoor space.
