Place the butterfly weed seeds in a plastic bag filled with 1 cup of moistened perlite. Store the bag inside the refrigerator for three months. Mist the perlite with water every few days to keep it from drying out completely.
Before you begin to harvest the butterfly weed pods, sterilize your cutting tools. Dip the blades into a full-strength household cleanser, such as Lysol or Pine-Sol. Repeat between cuts to prevent the spread of diseases.
Make a 1/4-inch-deep planting hole in the center of compost mixture. Drop one butterfly weed seed in the planting hole. Cover it with a loose layer of compost. Mist the compost to settle it.
Butterfly weed and milkweed seed pods may be harvested and planted to support Monarch butterfly caterpillars. Butterfly weed grows well from seeds, which must be harvested in late summer and either sown immediately in the garden, or started in spring after a lengthy chilling process. The seeds are viable and will germinate with little care, although they must be planted at the appropriate depth to ensure successful sprouting.
Leave the bucket outdoors for two or three days to let the fluff blow away. Stir the seeds occasionally to loosen more fluff. Do not worry if some of the fluff remains, since it won’t inhibit the germination process.
Prepare peat or other biodegradable pots before removing the butterfly weed seeds from the refrigerator. Fill 3-inch starter pots with a mixture of half seed-starting compost and half coarse sand. Moisten the mix and press it firm.
Watch for germination in two to three weeks. Turn off the propagation mat one week after the seeds sprout. Move the pots into a cold frame outdoors or against a south-facing wall with noonday shade.

Review By Timothy Gillane
Life Cycle: Perennial
I planted these late spring, and still got some good growth. At the end of summer, they’re starting to look pretty hardy. I even got a couple blooms, which is uncommon for first-year butterfly weed. I even found a couple monarch caterpillars hanging around!
Thank you Everwilde I am so pleased with your products and services. I have been using your farms for a few years and recommend you to all my friends. Fast service, great varieties, excellent seed packets and very good results when planted!!

Growing: Young plants should be watered until they become established; mature plants can tolerate drought, and the roots will be damaged by excessively wet soil. This plant grows slowly, and it may take 2-3 years to produce flowers. Though not invasive, this plant will eventually spread if left to drop its seed. The flowers attract bees, butterflies, and hummingbirds. Deer avoid this plant. If aphids become a problem, dislodge them from the plant with a strong stream of water.
Sowing: In late fall, direct sow butterfly milkweed seeds just below the surface. Germination will take place in the spring, after the last frost. When the seedlings appear, thin to the strongest plant; seedlings usually do not survive transplanting, since they resent any disturbance of their roots. For spring planting, mix the seeds with moist sand and refrigerate for 30 days before direct sowing.
