Swamp Milkweed (Asclepias incarnata) is a beautiful native perennial known for its clusters of soft pink to rose-purple flowers and its vital role in supporting pollinators. Thriving in moist soils and wetland conditions, this hardy plant is a must-have for butterfly gardens—especially for attracting monarch butterflies, which rely on milkweed as a host plant for their caterpillars.
Growing 3–5 feet tall, Asclepias incarnata produces fragrant blooms in mid to late summer that draw in bees, butterflies, and other beneficial insects. Its slender green leaves provide an essential food source for monarch larvae, making it both ornamental and ecologically important. Unlike some milkweed varieties, Swamp Milkweed has a more refined growth habit and is less aggressive, making it perfect for garden beds, borders, and rain gardens.
