✓NATIVE SWAMP MILKWEED SEEDS: HOME GROWN Swamp Milkweed Seeds (Asclepias incarnata) grow into tall native perennials with rounded clusters of rosy, soft pink, and mauve flowers. Also known as Swamp Rose Milkweed, plants provide summer-to-fall color across USDA zones 3–9.
✓IMPORTANT MONARCH HOST PLANT: Swamp Milkweed provides host foliage for developing monarch caterpillars, while its flowers attract adult monarchs, honey bees, native bees, and other beneficial pollinators. Ideal for monarch habitats, butterfly gardens, and pollinator plantings.
✓THRIVES IN MOIST AND WET SOIL: Unlike Common Milkweed, Swamp Milkweed tolerates consistently moist and wet conditions particularly well. Grow these native perennial flowers in rain gardens, bioswales, pond edges, wet meadows, and moisture-retentive garden areas.
✓COLD STRATIFICATION FOR GERMINATION: Cold stratify milkweed seeds for approximately 30 days before spring planting, or direct sow outdoors in late fall for natural winter stratification. After stratification, germination typically occurs within 14–30 days at 65–75°F.
✓PERENNIAL FLOWERS FOR ZONES 3–9: This cold-hardy perennial grows in full sun to partial shade and returns each year under suitable growing conditions. Provide moist, fertile soil and consistent moisture, particularly during germination and early plant development.
✓TALL NATIVE FLOWERS FOR LANDSCAPES: Mature Swamp Milkweed plants reach approximately 3–5 ft. tall with a 1–2 ft. spread, providing vertical structure for native gardens, wildlife habitats, moist perennial borders, and naturalized landscape plantings.
✓ROSE TO MAUVE FLOWER CLUSTERS: Rounded umbels approximately 2–3 in. across feature numerous small, star-shaped flowers in rosy, soft pink, and mauve shades. Blooms appear from summer into fall for seasonal color and valuable pollinator activity.
