Growing Swamp Milkweed:
Many gardeners recommend a cold treatment to help Butterfly Weed seeds germinate more quickly. To do this, dampen a paper towel, place the flower seeds on the towel and seal it in a ziploc bag. Place the bag in the refrigerator for 3 - 4 weeks. After the cold treatment, start the Butterfly Weed seeds indoors. Do not cover the flower seeds as they need light to germinate. Transplant the Butterfly Weed plants outdoors once temperatures are warm and the plants have 4 - 5 leaves.
