Butterfly Weed attracts truly a wide variety of pollinators making it so important ecologically. If you want to bring beautiful beneficial insects to your garden, planting Butterfly Weed is one the best native plants you can grow!

1 – Bees and Butterflies love it!
6 – Germination should occur within 21 days, once temperatures are above 70F
The sunlight requirements for Butterfly Weed are Full Sun or Partial Sun. Full sun is considered at least six hours per day of direct sunlight. While partial sun is 4-6 hours per day of direct sunlight.
After the flowers have faded seed pods will begin to develop in late Summer and into Autumn. Eventually the pods will turn brown and open up, releasing Butterfly Weed seeds into the wind.
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.
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.
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.
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.
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.
Snip off the pod using pruning shears. Slice lengthwise along the edge using a utility knife. Pry open the seed pods. Scoop out the seeds and fluffy matter inside and place it in a bucket.
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.
