butterfly weed seeds harvesting

I live and garden in Minneapolis, MN (zone 4b). My green thumb comes from my parents, and I’ve been gardening most of my life. I’m a passionate gardener who loves growing everything from vegetables, herbs, and flowers to succulents, tropicals, and houseplants – you name, I’ve grown it! Read More.

If the milkweed bugs are now on my plants, does that mean the seeds I can see are no good?

How To Harvest Butterfly Weed Seeds Step-By-Step

So I have cuttings from a butterfly weed perennial. I was hoping to be able to repurpose the flower or stem to plant in my garden at home. Am I out of luck? Will I have to buy the seeds to plant in the fall?

Clip the seed pods off the plant and drop them into a container or bag. Don’t attempt to harvest butterfly weed seeds outside.

You can store your seeds in a plastic container (film canisters are the perfect size!), paper bag or seed envelope until spring.

Transplant the butterfly weed into a permanent bed in spring just after the last frost. If planting butterfly weed in clay soil, dig in 2 to 4 inches of compost to lighten the soil, or consider building raised beds to increase drainage.

Arrange the starter pots on a propagation mat near a source of bright, indirect light such as near a partly shaded south-facing window. Set the temperature on the propagation mat to 86 F during the day. Turn it off at night.

Gather the butterfly weed seeds in late summer or autumn, once the pods dry to a light, rosy-beige color, but before they split open. Put on rubber gloves before handling the pods to protect your hands from the mildly toxic sap.

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.

Sometimes called pleurisy root, butterfly weed (Asclepias tuberosa) is a perennial wildflower grown for its showy, reddish-orange flower clusters and textured, lanceolate leaves. A member of the milkweed family, it thrives throughout U.S. Department of Agriculture plant hardiness zones 3 to 9, where it is frequently added to butterfly gardens and native plant landscaping.

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.

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.

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.

Latin Name: Asclepias tuberosa

Seed Saving: After the plant finishes flowering, 3-4″ narrow pods will form. Be sure to harvest butterfly milkweed pods before they split and the silky fluff carries the seeds away on the wind. As soon as the seeds inside the pod ripen to their mature brown color, remove the pods and spread them out to dry. Split open the pods and take out the silky seed material. Remove the fluff from the seeds. Store the seeds in a cool, dry place.
