butterfly weed seed pods

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.

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.

Water the butterfly weed seeds whenever the compost feels barely damp when pressed. Apply the water by the spoonful or use a spray bottle to keep from dislodging the seeds.

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.

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.

Then firmly grab the entire fuzzy clump and pull it out of the seed pod. Wait, don’t let go.

Butterfly weed is one of my favorite plants that I have growing in my garden. Not only does it add amazing color to the garden, the butterflies flock to it. Plus, it’s a host plant for everyone’s favorite monarch butterfly.

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

The seeds are white not seed pod, my bad!
