Rose Swamp Milkweed
Best native perennial for gardeners supporting Monarch butterflies in wet soil.
The Rose Swamp Milkweed, Asclepias incarnata 'Rose', is a vibrant perennial celebrated for its beautiful pink blooms and vital role in supporting Monarch butterflies. This native plant thrives in moist to wet conditions, making it ideal for rain gardens. It's a crucial food source for Monarch caterpillars and a nectar haven for adult butterflies, bees, and hummingbirds. Generally resistant to deer and rabbits due to its milky sap, it offers summer blooms and attractive seed pods for winter interest. Patience is key, as its deep taproot may lead to a later spring emergence.

Know before you buy
While it thrives in moist to wet soil, it is quite adaptable and performs well in standard perennial beds as long as they receive consistent moisture. It is an excellent choice for rain gardens or low-lying areas of your landscape that tend to hold water.
Rose Swamp Milkweed is a late riser. Because it develops a deep taproot, it waits for the soil to warm up significantly before sending up new growth, so don't be alarmed if it appears later than your other perennials.
No, this plant is generally resistant to deer and rabbits. Its milky sap makes the foliage unpalatable to these animals, helping it remain undisturbed in your garden.
No, Rose Swamp Milkweed is not considered pet-safe. It contains cardiac glycosides, which can be toxic if ingested by dogs or cats, so it is best planted in areas where your pets do not graze.
With a mature spread of 36 inches, you should space your plants about three feet apart. This allows for proper air circulation and ensures the plants have enough room to reach their full height of 3 to 4 feet.
Yes, once the flowers finish, the plant produces attractive seed pods. These pods add structural interest to your garden throughout the fall and winter months.
