How to Grow:
For natural stratification, sow seeds outdoors in the fall in moist, sunny soil, lightly covering them with earth. For indoor sowing, start in February. Use a soilless mix and stratify seeds in a refrigerator for 3 months. Then, place them at 20°C to germinate in 10 to 18 days. After germination, grow under lights at a cooler temperature, and harden off seedlings before transplanting to a sunny, moist location.
Swamp Milkweed is a must-have for pollinator-friendly gardens, combining beauty and ecological utility by supporting monarch butterflies and other beneficial insects.
