Site Selection

These North American native milkweeds are hardy perennials that will tolerate full sun to partial shade and thrive in a wide variety of soils.


For best results, expose seeds to moist, cold conditions (stratification) prior to sowing. For cold stratification, place seeds in moist potting soil or sand and store in a refrigerator for 4-6 weeks. After stratification, sow seeds in containers or direct seed outdoors after the danger of frost has passed. Sow seeds 1/8-1/4" deep and 6-8" apart. Optimal soil temperature for germination is 65-80˚F. Seeds will sprout in 10-28 days. Thin seedlings so that mature plants are 24-36" apart.

Seeds can also be direct sown outdoors in the fall where they will stratify naturally and germinate the following spring.

    Butterfly Milkweed is growing in our schoolyard garden. Go to the Mullica Township Schoolyard Garden Facebook page to see some photos. Our students started it from seed inside and planted it outdoors in May. We had great success.
