How to Start
-
For spring planting, cold-stratify the seeds in a slightly moist medium in the refrigerator for approximately 30 days.
-
Sow seeds about 1/4 inch deep in a well-draining seed-starting mix or directly outdoors after stratification.
- Keep the soil consistently moist during germination, but avoid waterlogging.
- Provide plenty of light and warm conditions after the cold treatment.
-
Germination commonly begins within 1–3 weeks after proper stratification and sowing.
- Once seedlings are established, transplant them carefully into a sunny location with good drainage.
Set expectations: Germination and growth can vary depending on seed freshness, stratification, soil temperature, moisture, and local conditions. Showy Milkweed is a spreading perennial and may expand through underground rhizomes once established.
