swamp milkweed

Asclepias incarnata


Swamp Milkweed is a beautiful, hardy native perennial prized for its soft, fragrant pink flower clusters and its vital role in supporting pollinators. Blooming in mid to late summer, it adds height, color, and movement to gardens while serving as a crucial host plant for Monarch butterfly caterpillars. Swamp Milkweed thrives in consistently moist soils but also performs well in well-drained, average soils and typical garden conditions once established. Dry soil should be avoided. It is heavily sought after by those who want a Milkweed plant that can thrive in even the most stubborn wet and heavy-clay soils. Its upright growth habit and narrow leaves also add to its aesthetic allure. This species of Milkweed is an excellent choice for rain gardens, pollinator borders, meadow plantings, and water edges. Swamp Milkweed is overall low-maintenance, valuable for various native pollinators and other wildlife, and has been known to be deer-resistant.
