Fragrant, rose-pink, nectar-rich flower clusters atop tall, sturdy stems give Swamp Milkweed a stately presence in the garden or meadow. A favorite of many pollinators, Milkweeds (Asclepias) are the host plant for Monarch butterflies, and the sweet pink blooms will be buzzing with activity. These impressive native wildflowers feature narrow, tapering foliage, and mid-to-late-summer blooms are followed by attractive seed pods that add interest to the fall garden. Thanks to its bitter milky sap, Milkweed is deer and rabbit resistant. (Asclepias incarnata)

As the common name suggests, Swamp Milkweed is native to wet meadows and riparian zones throughout eastern North America. Growing along streambanks and pond edges, Swamp Milkweed looks right at home alongside water features, and its tolerance to wet soils makes Swamp Milkweed useful in rain gardens, bioswales, and other wet spots in the landscape. However, plants can also thrive in well-drained garden soils. Asclepias incarnata plants have a clumping habit and naturalize well in the landscape. Milkweed serves as a larval host to monarch and queen butterflies, so look for caterpillars munching on the leaves in early summer. In addition to butterflies, the blooms provide a valuable nectar source to honeybees, bumblebees, and other pollinators, and are occasionally visited by hummingbirds. Plants will perform best in full sun in moist clay, loamy, or average soils, in hardiness zones 3 to 6. Plants have deep taproots and are best left undisturbed once established. Be patient, as they are slow to emerge in spring.
