Swamp Milkweed

About this plant

Known for its stunning clusters of rose-pink flowers, Asclepias incarnata, commonly called Swamp Milkweed, is a vital plant for any pollinator garden, especially for those looking to support monarch butterfly populations. Unlike its common name suggests, it thrives not only in swampy conditions but also in average garden soils, as long as consistent moisture is provided. Blooming from mid-summer through early fall, its fragrant flowers provide an abundant nectar source for a variety of butterflies, bees, and other beneficial insects. Its leaves are the sole food source for monarch butterfly caterpillars, making it an essential host plant for their life cycle. Easy to grow and maintain, Swamp Milkweed adds both beauty and ecological value to rain gardens, naturalized areas, and mixed perennial borders. It's a robust plant that tolerates a range of conditions and will return year after year.

Installation timing

When we're in season, outside of the winter months, our goal is to get your plants installed within about two weeks. That window gives us enough time to secure your plants from our supplier and find a spot on the schedule. Throughout the process we stay in touch through notifications and your existing client portal on the main A Cut Above website, which is separate from this landscaping plants shop.

Care & maintenance

Requires consistent moisture, especially during dry periods. Can tolerate short periods of drought once established, but performs best with regular watering. Deadhead spent flowers to encourage new blooms and prevent unwanted self-seeding. Cut back in late fall or early spring.

Watering suggestions

Proper watering is the single most important factor in your plant's survival after installation. Newly installed plants have a limited root system and rely on you for consistent moisture while they establish.

• First 2 weeks: Water deeply every day (or every other day in cooler, wet weather), soaking the root ball and surrounding soil.
• Weeks 3–12: Water deeply 2–3 times per week, adjusting for rain, heat, and soil drainage.
• After establishment: Water deeply about once a week during the growing season, and more often in extreme heat or drought.
• How to check: Stick a finger 2–3 inches into the soil near the roots — if it's dry, it's time to water. Deep, less-frequent watering encourages strong roots; shallow daily sprinkles do not.
• Avoid: Overwatering (soggy, waterlogged soil) is just as harmful as underwatering and can drown roots.

Watering needs vary by plant, season, soil, and exposure. Because proper watering is the customer's responsibility after installation, please make sure you understand and can follow these suggestions before ordering.

Good to know: plants and trees purchased from and installed by A Cut Above include a one-year limited warranty from the date of installation. Because plant survival depends heavily on proper watering and care after installation, losses caused by improper care, neglect, animal or chemical damage, or extreme weather are not covered, and we must be given the chance to inspect a struggling plant before it's removed or replaced. Coverage is one replacement per plant. Read our warranty info.
