when to plant butterfly weed seeds

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.

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.

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.

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.

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.

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.

Beloved for its ability to attract a variety of helpful (and beautiful) insects to the garden, Butterly Weed is an easy-to-nurture varietal that can also be found growing as a native wildflower in a slew of untamed environments, like meadows, prairies, and forests. Typically grown from seeds you sow directly in the garden in the fall, the butterfly plant does not require much tending to in order to thrive, prospering well in everything from clay soil, to dry or rocky soil, and even throughout drought-like conditions. Its seed pods will brown towards the end of its growing season (early autumn) and, if left on the plant, will burst and spread seeds throughout your garden to emerge as new growth the following spring. While the plant can take up to three years to fully mature and produce flowers, its blooms will gradually grow denser with each season that passes.

Chances are there are more finicky flowers in your garden than the Butterfly Weed, so feel free to allow them to dictate the soil composition—when it comes to this plant, you don’t have to stress. Butterfly Weed can prosper in a variety of soil conditions and compositions, from clay to gravel, and generally prefers a neutral to slightly acidic pH.

Typically, the easiest and most successful way to add Butterfly Weed to your garden is to grow it from seed form. Plant fresh seeds in fall for growth the following spring, or allow any established Butterfly Weeds already in your garden to do the work for you. Beginning in late summer or early fall, the plants should start to develop seed pods in place of their blooms. If left on the stem, the pods will eventually burst and the seeds inside will be blown throughout your garden, allowing them to establish themselves in the soil in time for the following year. If you’d rather have more control over the eventual location of any new Butterfly Weed plants, you can remove the seed pods from the plant before they burst open and simply plant new seeds by hand instead.

The low maintenance Butterfly Weed does not require any additional fertilization—in fact, doing so can harm the plant, so it’s best to just let it do its thing.

Butterfly weed is a must-have plant for green thumbs looking to coax its namesake beautiful winged insects into their garden. Also known as Asclepias tuberosa, orange milkweed, pleurisy root, and yellow milkweed, the plant can grow to be anywhere from one to two feet tall and is characterized by glossy green leaves and clusters of bright orange-to-yellow blooms that are rich with nectar and pollen, which in turn attracts butterflies, along with bees, insects, and hummingbirds, all summer long. First grown in the prairies of the Midwestern United States, Butterfly Weed boasts a long medicinal history as well—Native Americans used to chew the roots as a remedy for pleurisy and other pulmonary issues, and they can also be brewed into a tea that can then be used to treat diarrhea and other stomach ailments. Butterfly weed should be planted in the early spring (after the final frost)—it will be slow to emerge, but will grow quickly once it does, hitting peak height and bloom in mid-to-late summer.
