Swamp Milkweed, also known as Rose Milkweed, is native to most of the continental U.S. and eastern Canada. Its vanilla-scented, vibrant pink blossom clusters will bloom all summer.

Planting & Harvesting

Seed Depth: 1/4″ (6mm)
Spacing: 1″ (3cm)
Sprouts In: 14-28 days
Thinning: 1-2′ (30-60cm)

For best results, sow outdoors in late fall in a well-drained, sunny area. Start indoors two to three months before last spring frost. Seeds started indoors and sown in spring must be cold treated (stratified) for proper germination. Place in cold, moist, sterile potting soil in a dark place, or between moist papers towels in a plastic bag stored in the refrigerator for six to eight weeks before planting. Soak refrigerated seeds in warm water for 24 hours before planting.

Swamp Milkweed requires more water than other Milkweed varieties.
