• 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 monarch butterfly 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. These native perennial flowers are suited to rain gardens, bioswales, pond edges, wet meadows, and moisture-retentive landscape 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 in suitable growing conditions once established. Provide moist, fertile soil and consistent moisture, particularly during germination and early plant development.
• TALL NATIVE FLOWERS FOR LANDSCAPES: Mature Swamp Milkweed plants grow approximately 3-5 feet tall with a 1-2 foot 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 inches across feature numerous small, star-shaped flowers in rosy, soft pink, and mauve shades. Blooms appear from summer into fall and provide seasonal color alongside valuable pollinator activity.
• IDEAL FOR RAIN AND NATIVE GARDENS: Grow Swamp Milkweed in monarch waystations, pollinator gardens, native plantings, rain gardens, bioswales, wetland edges, pond borders, and wet meadows where its moisture-loving habit provides both ornamental and habitat value.
• SIMPLE PLANTING AND CARE: Sow seeds approximately 1/4 inch deep and space plants 1-2 feet apart. Keep soil consistently moist during germination and establishment, and avoid allowing young plants to dry completely while their root systems develop.
• 1,000 HEIRLOOM NON-GMO MILKWEED SEEDS: Each bulk Mylar pack contains approximately 1,000 heirloom, non-GMO Swamp Milkweed seeds (Asclepias incarnata) weighing 4.4g, providing a generous quantity for larger monarch habitats, rain gardens, native plantings, and pollinator landscapes.
