Showy Milkweed Asclepias is an ornamental native wildflower. It's perfect for home landscaping and use in the butterfly garden or prairie meadow, and it attracts hummingbirds as well. People have also used milkweed for fiber, food, and medicine all over the United States and southern Canada. Milkweeds (especially Asclepias speciosa) supply tough fibers for making cords and ropes, and for weaving a coarse cloth. It is a very versatile plant that is easily grown from flower seeds!
Growing Showy Milkweed from flower seed is very rewarding. It is appropriate to sow Asclepias seeds outdoors after the frosts of fall have begun. The cold, dormant planting will aid the germination of the seed in spring when temperatures warm. If sowing Milkweed seeds indoors or in a greenhouse, refrigerate the seed for 2 months before sowing. The cold treatment will help to break the dormancy of the seed.
