Asclepias incarnata

Common Name: Swamp Milkweed

Asclepias incarnata, commonly known as Swamp Milkweed, is a perennial plant that grows 1 to 4 feet tall. It has narrow, lance-shaped leaves and produces clusters of fragrant pink to mauve flowers from June to September. Swamp Milkweed thrives in moist to wet habitats such as wetlands, marshes, and along shores, preferring loamy or sandy soils. It is highly attractive to monarch butterflies and other pollinators, serving as a host plant for monarch caterpillars. In landscaping, Swamp Milkweed is valued for its showy flowers and suitability for rain gardens and wetland restoration projects.

Sowing Information

For most homeowners, the recommended method is to hand-broadcast seed at a minimum rate of 16–64 PLS (Pure Live Seed) ounces per acre. To ensure even coverage, broadcast the seed in perpendicular passes across the site. Grass seed should be broadcast first and lightly raked into the soil. Afterward, apply a light mulch layer using clean, seed-free straw or, preferably, our native Little Bluestem straw, available at our retail garden centers. Once mulching is complete, broadcast native wildflower seed over the area without raking it in. A good rainfall or thorough watering will provide sufficient soil contact for successful germination.

Planting Information

Dig a hole in your planting site slightly larger than the plant’s root system. When placing the plant into the hole, ensure that the soil line remains consistent with its original level in the pot. Fill in around the roots with the excavated soil, gently firming it to eliminate air pockets. Water the plant thoroughly the same day to promote successful establishment.
