How to Grow Joe-Pye Weed in Your Landscape or Garden

Skipping over all the heated arguments about flowers, snobbery, and who has the audacity to call certain plants “weeds,” I’ll tell you that joe-pye weed is wonderful.

It grows tall, seven feet or more, and blooms in late summer and fall when so many other flowers have already faded.

Its composite flowers, in attractive shades of purple, pink, and pearl white, have a scent reminiscent of vanilla.

They produce an abundance of nectar and pollen that attracts and provides for butterflies, particularly swallowtails, and various other types of pollinators.

The seeds, especially since they form so late in the fall, appeal to songbirds in search of food.

Joe-pye has a couple of especially desirable traits you don’t come across that often.

For one thing, it will thrive in moist areas, which is why you may have spotted it growing in ditches alongside the highway, and why you might want to plant it in problematic swampy areas of your yard.

And its USDA native status extends throughout the lower 48 states, so it’s appropriate for meadows, butterfly gardens, and other native landscaping plots across the country.

Whether you’re looking for a tall plant that’s easy to care for, or you’re trying to attract wildlife and love a vanilla aroma, joe-pye weed may be just the thing.

There are even more benefits to discover in this guide, along with plenty of growing advice. Here’s what to expect:

What You’ll Learn

What Is Joe-Pye Weed?

Part of the aster family, Asteraceae, and native to North America, the five species commonly called joe-pye weed are late summer and fall-blooming wildflowers that thrive in sunny, moist sites.

They readily self-seed, and some species also spread underground via rhizomes.

Most grow tall, to a mature height of seven feet or more, but some of the cultivars developed more recently are shorter and more appropriate for smaller garden beds, reaching three to five feet tall.

They typically bloom in purple or dusky white, though some varieties have off-white blossoms.

Each flower is a composite, flat-topped cluster of nine to 22 tubular florets with a pithy center.

Along with being irresistible to bees, the abundant nectar attracts hummingbirds, and songbirds flock to the blooms to eat the insects they draw.

When the flowers fade in late fall, they produce seeds for the birds to eat, and little fluffy puffs (known as pappi) that may be used as nesting material.

All these traits make joe-pye a darling of naturalists and gardeners in search of hardy native plants for the fall landscape.

How did this species get such an unusual name? Read on for more info about that, and learn all the dos and don’ts for growing this wonderful wildflower.

Cultivation and History

I love a good story as much as the next person, but it’s most likely just folklore that the original Joe Pye was a native healer who would cure typhus with Eupatorium purpureum.

That plant was once classified in the same genus as joe-pye weed, and is now known commonly as boneset (Eupatorium perfoliatum).

The tale of the New England herbal healer has been making the rounds of wildflower guidebooks for at least 120 years.

Another amusing but unlikely addition to the background of this species says the former genus Eupatorium has a name derived from a king known as Eupator Dionysius.

He was born around 120 BC, and may have used a poison antidote derived from plants of that type to condition himself to withstand the effects of poison later used to kill his enemies.

Some recent and aboveboard research from botanists James S. Pringle and Richard B. Pearce did establish the existence of an authentic Joe Pye.

That was the nickname used by Joseph Shauquethqueat, a venerable Mohican chief who lived in New England in the late 1700s and early 1800s.

So far, though, the relevance of this chief’s connection to the plant species has not been conclusively established.

The catchy common name has been applied to these wildflowers since at least 1818, when it was recorded in Amos Eaton’s work, “A Manual for Botany for the Northern and Middle States.”

In the intervening centuries, many more species of joe-pye weed have been identified. In a bold and sweeping move, botanical taxonomists made a necessary distinction in 2012, moving five species associated with this moniker to the genus Eutrochium.

Mind you, there are still plenty of herbalists today who will tell you about that typhus-curing connection, and many of those who sell or describe these plants still use the Eupatorium label. (I think of this as being similar to some who never converted to the metric system, not as evidence of ill intent.)

Today, whatever the path taken to arrive at that name may have been, these plants are widely appreciated as part of an “old is new again” movement towards native landscaping, and creating pollinator and butterfly gardens.

You can appreciate this appealing though inconclusive backstory, the tough nature of these naturalized plants, their late-blooming show of color, or all of the above.

Whatever draws you to wanting to grow your own healthy joe-pye plants, be it the name or the benefits, we’ve got the step-by-step instructions right here. Let’s get growing!

Propagation

To grow your own joe-pye weed, you’ll need a site that has ample moisture and receives full sun to part shade – more light is preferred, for abundant blooms.

The soil should be fertile and amended with plenty of compost, whether loam or clay. With those requirements in place, here’s how and when to plant:

From Seed

Unless you have a handy source of divisions, or are content with purchasing a few nursery plants, the best way to start more than a couple of these statuesque wildflowers at a time is by planting seeds.

To most closely mimic the natural growing conditions for these native plants, sow the seeds in late summer or early fall, so they can chill properly during the cold months. Keep them moist until they sprout in early spring.

To sow, press them into the surface of soil that has been cultivated a few inches down. They need light to germinate, so don’t cover them with soil.

Plant about seven seeds in groups two or three feet apart, to accommodate joe-pye weed’s low germination rate.

If more than one seed does sprout in a given spot, when the seedlings produce two pairs of true leaves, you can clip the smallest at the soil line and leave the healthiest to grow on.

The final spacing should allow between two and four feet between plants, depending on the variety.

You may want to apply a lightweight row cover after planting to keep birds from eating the seeds.

Late summer or fall-planted seeds will sprout in early spring. They may bloom that first year, but don’t worry if they hold off until their second growing season to produce flowers. Either timeline is within their typical range.

You can start seeds indoors, but then you’ll need to provide the seeds with the requisite period of “cold stratification,” instead of relying on the wintry weather.

That just means pressing the seeds into the surface of pots of moist soil, popping them into plastic zipper bags, pots and all, and leaving them in the fridge for 30 to 60 days before growing them indoors to plant out in spring.

It’s also possible to store just the seeds in the fridge from fall until spring temperatures are suitable for outdoor sowing, but it’s less likely you’ll get blooms in the first year with this approach.

From Divisions

Divisions can be made from your own mature plants, or you can source donations from a friend.

Make sure your garden bed or other area of the landscape is already prepared with compost and moist soil to receive the new plant.

The stems can only survive out of the ground for a few hours after dividing, and even then you’ll need to wrap the roots gently in a moist towel until you can get them into the soil.

To propagate joe-pye weed from divisions, divide mature plants in the fall as they go dormant. Or, you can wait to divide them until the spring when they begin to send up shoots.

Use a spade to dig out the whole plant and rest it on the ground.

Look for the wide crown of the mature plant. It will have several stems and a tangled root system.

Each piece of stem can become a new plant, but only take half of the total plant for divisions at most, so the parent plant can adjust more readily.

Thrust a sharp-ended trowel downward a couple of inches to separate a stem from the crown, cutting the attached roots at the same time. Gently bring that piece to the surface, and then replant it in its new location.

Plant it at the same depth it was growing when it was part of the parent plant.

Water it in and apply a couple of inches of pesticide- and herbicide-free mulch in a circle a couple inches away from the stem, to keep the soil moist until the plant gets established.

Unless you’re trying to relocate it as well, set the parent plant back in its original hole, and take this opportunity to add a bit of compost when you backfill the opening.

From Transplants

If you buy plants from a nursery or grow seedlings indoors, you can add them to the landscape or garden in late summer or early fall.

To transplant, prepare the bed as you would for seeds or divisions.

Dig a hole for each plant that’s at least three feet from its nearest neighbor, and a little larger than the root ball of your transplant.

Gently tip the plant out of its pot and set it into its hole with the top of the root ball positioned at soil level. Add the same rich, compost-amended soil to fill the hole, tamp lightly, and water deeply at the soil line – not from overhead.

You may also want to mulch transplants with a couple inches of organic material that hasn’t been treated with potentially harmful chemicals, like straw.

Place it a few inches from the center stem. This will help to keep moisture in without killing off the pollinators this wildflower attracts in swarms.

How to Grow

You’ve been promised practically carefree plants, and joe-pye will deliver.

You will need to keep seedlings moist for the first year until they get established, but after that, they can survive a dry spell now and then.

Just make sure to give the plants about an inch of water if it hasn’t rained in any given hot-weather week.

If you’ve planted them in the woods or a meadow, don’t worry about fertilizing these wildflowers.

But when you’re growing in poor or average soil in a garden bed, they will benefit from a side dressing of compost or an application of slow-release fertilizer. Do this chore in early spring, as the perennials are sending up new shoots.

One more thing: Weeds are a problem for young seedlings. They will compete for the water the plants need.

Mulch will keep the weeds down while helping to retain moisture in the soil. If weeds do appear, make sure to pull them.

Growing Tips

• Plant in full sun to part shade.
• Press seeds into the soil surface – they need light to germinate.
• Only grow where the plants will have three feet to spread.
• Keep the soil moist, especially in the first year.
• Prevent weeds with mulch.

Pruning and Maintenance

One maintenance chore when growing joe-pye involves constant deadheading, if you’d prefer that your plants not self-seed.

Note that this won’t encourage new blooms the way it would for some other types of flowers, like bachelor’s buttons, but you will be able to prevent aggressive spreading if that’s your wish.

Wait for the flowers to die first, but perform this task before they become brown and dry, and produce seeds the wind is only too happy to carry to exposed earth elsewhere in the yard or garden.

I’m not the type to fuss like this over a native plant, and I consider their impressive height to be an asset, but some gardeners also like to prune joe-pye a bit later in the growing season.

Clipping the top third of the plants will encourage them to branch more fully and attain a shorter height.

As the blooming season comes to a close, if you object to the appearance of sprawling, dried-up wildflowers in your landscape, you can also trim the spent plants without hurting them.

Do this in late autumn, using clippers and leaving the bottom four to eight inches in place.

Joe-pye goes dormant in the winter, and the leaves will turn black after a hard frost or two. You can clip them at this point if you like, but it’s strictly cosmetic, since the wildflower will grow back with or without the unsightly dead foliage attached.

When your plants are part of a native landscaping scheme or a wildlife garden, you may want to forgo cutting down the dry stalks and leaves.

They provide shelter for songbirds in cold weather, and the stalks give beneficial insects a spot for overwintering.

Other than clipping for cosmetic reasons, these species are hardy wildflowers, and they can pretty much take care of themselves over the winter.

Once they’re three years old, and every few years after that, it’s a good idea to divide them. This will keep the root mass from growing so large that the center of the plant dies off because it’s no longer getting the nutrients it needs.

Dividing is also a good way to stop the plants from spreading too far, or for providing yourself with some starts for transplant.

Time the job for early spring, just as they’re sending up new growth.

With a sharp-edged spade, dig out the entire plant, along with an extra two inches of soil around the perimeter. Thrust the spade into the ground at a right angle, moving all around the plant until the root mass can be lifted.

Ease the whole plant and its root system out of the ground in one big clump.

Then lay it on the soil next to the hole, and use a pruner or soil knife to sever the roots into several pieces, making sure each has stalks attached.

Wearing gloves, gently work the pieces free of each other. Transplant them immediately, following the directions outlined above.

And hey, if you’re the type who can’t wait to plant more and more joe-pye and would like to save seeds in addition to making divisions, you can do that as well!

Start about a month after the flowers have stopped blooming, once you can see that they’re dry and brittle and have turned brown. Use scissors to sever the entire seed head from the stalk.

Place it into a brown paper bag and set it in a cool, dry spot for about three more days to dry completely.

Pluck the seeds off the heads and store them in the fridge in a zipper bag, small canning jar, or plastic container. Leave the seeds in the refrigerator right up until you’re ready to plant next season.

Species and Cultivars to Select

While there are also some unique cultivars available, some of them bred to resist powdery mildew, these four species within the Eutrochium genus offer a good place to start when you are selecting a type to grow.

Botanical taxonomists moved each of these from the genus Eupatorium in 2012, which is so recent that you can still expect many people to refer to them by their former names.

Each of these is commonly referred to as “joe-pye weed,” with perhaps another more specific nickname in use as well, and has a few distinct characteristics to consider. Here’s the scoop:

E. dubium

This species has the intriguing alternative name of “three-nerved joe-pye weed.” A dwarf species that usually grows just three to five feet tall, it can thrive in smaller areas, but still spreads between two and four feet.

The stems are purple-spotted, the leaves are yellowish-green with three deep veins apiece, and the flowers form domed clusters of pale pink to purple florets that are four to seven inches wide.

E. dubium plants are hardy in Zones 4 to 8. ‘Little Joe’ plants are available from Burpee.

E. fistulosum

Known as hollow stem joe-pye weed, E. fistulosum sports muted pink or purplish flowers in clusters that can reach 18 inches across. It’s a butterfly smorgasbord with all that nectar.

The plants grow four to 10 feet tall and spread two to four feet. They are hardy in Zones 4 to 8.

As for that nickname, the smooth, light green stems are indeed hollow. If you leave them alone and let them dry at the end of the season, solitary bees will sometimes seek them out as a place to reside and lay eggs.

‘Alba’ is an attractive option, with white flowers if you’re looking for something a little different.

E. maculatum

Referred to as spotted joe-pye weed, this variety has stalks that are purple or green with purple speckles, hence the nickname.

The mauve or purple flower heads are nearly flat.

E. maculatum is hardy in Zones 4 to 8, and grows three to six feet tall.

“Seed bombs” that include seeds, compost, and soil are one buying option for this variety. They are available in 20-, 50-, 100-, and 200-seed ball packets from Seed-Balls.com via Amazon.

Sometimes listed under other species names, ‘Gateway’ is a popular cultivar.

E. purpureum

Monarchs are just one of the types of butterfly that find E. purpureum so appealing. The vanilla scent is particularly strong in this variety, and the aroma wafting on the breeze attracts butterflies and other pollinators.

Hardy in Zones 4 to 9, this plant, commonly referred to as sweet joe-pye weed, grows to between three and seven feet tall. Its textured leaves are grouped three or four to a whorl, on green stalks.

The leaf joints are purple and they sport delicate hairs.

E. purpureum seeds are available in 120-seed packets from Zellajake Farm and Garden via Amazon.

Managing Pests and Disease

This easy-care wildflower is mostly free of insect problems, and is even resistant to those persistent four-footed pests, the deer and rabbits.

It also eludes most diseases, though you’ll want to watch out for powdery mildew, caused by Golovinomyces orontii.

This fungus can overwinter in soil and spreads its spores via wind. It thrives in high temperatures and intense humidity.

Powdery mildew will appear on foliage as patches of gray-white mildew, and it can harm the wildflower’s ability to get the nutrition it needs via photosynthesis.

To avoid powdery mildew, make sure your plants have plenty of room to grow. Ample air circulation will stop this fungal infection before it starts.

Also avoid watering from overhead, to keep relative humidity lower near the susceptible foliage.

When you grow joe-pye in part shade, there’s a higher risk of powdery mildew, which prospers in low-light conditions. If it’s a persistent problem, consider moving your plants to a sunnier spot.

To keep powdery mildew from obliterating plants that are growing in less substantial light, make sure to observe them often, especially when humidity becomes a factor in the warm months.

If just a few leaves are affected when you notice the splotches, you can clip them off and dispose of them in the trash, and that will probably take care of the problem.

Should you only spot powdery mildew after it’s established a stronghold, fungicides like neem oil can be effective.

Safer Brand Horticultural & Dormant Spray Oil Concentrate is a good option for organic gardens. It’s available in a 16-ounce concentrate from Safer Brand via Amazon.

Though it is not considered common, a 2006 report noted that wild joe-pye weed may serve as a host to tobacco ringspot virus, and the virus can live on plant debris and seeds.

This disease may be transmitted via contaminated tools or hands, and it causes stunted growth, yellowing, and a mottled appearance on leaves, as well as leaf rolling.

Affected plants should be removed from the garden and destroyed.

Best Uses

When you’re employing joe-pye in your garden or landscape, if you have space and can keep the plants moist, the best uses are limited only by your imagination.

Each plant must have at least a couple of feet between it and the nearest plant, wall, or tree, with ample moisture.

Beyond that, though, it’s a beautiful and beneficial addition to native plantings, butterfly gardens, and perennial meadows.

Use the height to complement shorter flowers or ornamental grasses in complementary colors.

This wildflower blooms late in summer and fall, so consider it to continue the show of color when short-season annuals in the garden have gone to seed.

It’s also an MVP at the back of borders or, with its affinity for wet soil, it can be planted in a swampy patch of yard. Consider growing it near a rain spout to disguise the eyesore while the roots drink up any standing water.

One other tip: If you’re employing this pollinator- and songbird-magnet to attract wildlife, see if you can’t place it within view of a window, patio, or porch. That makes it easy to watch the pollinator show from a comfy spot.

Tom’s Blog

Yesterday I spent an hour or so collecting woodland Joe Pye weed ( Eupatorium purpureum ). This species is relatively similar to the wetland Joe Pye weed ( E. maculatum ), but less colorful and better adapted to woodland areas. It is a strikingly tall species that has become established in those parts of our savannas which have more closed canopy (50% or even a bit more).

The best stands of E. purpureum are north of our North Fire Break, just before the steep drop off into the oak woodland. I used the Kawasaki Mule to get in there, and it was an enjoyable day, quiet and peaceful. I got two buckets full of seed heads.

Although the flower heads seem fairly dry, they still need to be dried a few days by spreading them out on a tarp. Once dry, the seeds must be cleaned before using. It is fairly easy to clean the seeds. Just put the flower heads on top of a piece of fairly course screening (available from a hardware store) and scrape them back and forth. The seeds fall through, and the empty stems can be thrown away. Store the seeds in a dry place in a grocery bag until time to plant.

While I was seed collecting, I was also keeping my eye out for small buckthorn that needed spritzing or basal barking. Fortunately, the buckthorns were fairly scattered here, and I proably only treated a couple dozen plants. I carried a spray bottle in my belt pack. We’ll be back in this area in the winter for more extensive buckthorn work. Hopefully, this will be a low snow year so that we can get some work done!

How to Gather & Sow Seeds From Joe Pye Plants

Joe Pye weed (Eupatoriadelphus fistulosus) is a wildflower native to the eastern half of the United States in USDA horticultural zones 3 to 9. It grows to 6 feet tall and has a hollow stem with large oblong leaves up to 10 inches long. The plants can form dense colonies if grown in the right conditions–damp or wet rich soils. The flowers are attractive to a number of butterflies, and the plant can produce flowers during most of the growing season if conditions are suitable. Several improved varieties are available with brighter or darker blooms than the wild version.

Collect Joe Pye weed seeds by finding flower heads that are faded and dry and you can plainly see the tiny thin seeds still attached to the base of the flower heads. Each seed has a tiny bit of fluff attached to it so the wind can carry it away from the mother plant. Carefully cut the stem below where the seeds are attached to the old flower head with hand shears and place the old flower head in a paper bag. Seeds are usually available for harvest in late summer and early fall.

• Joe Pye weed (Eupatoriadelphus fistulosus) is a wildflower native to the eastern half of the United States in USDA horticultural zones 3 to 9.
• The flowers are attractive to a number of butterflies, and the plant can produce flowers during most of the growing season if conditions are suitable.

Shake the seed from the flower heads and store the seeds in the paper bag in a cool (60 to 75 degrees F) location. Store for as long as four weeks without refrigeration if you are planning on planting the seeds in the fall. If you are planting the seeds in the spring and holding them over the winter, store in an open paper bag in the refrigerator for at least six weeks. The cold temperatures increase the sprouting or germination rate.

Locate an area of the garden that stays moist and receives up to six hours of sun each day. Good air circulation around the planting bed is encouraged as Joe Pye weed is susceptible to mildew diseases. Joe Pye weed does not like weed competition, so make your planting area no deeper than 2 feet if planting against a wall or fence or 4 feet wide if planting in beds that have access on both sides. The reason for this is so you can reach into the beds and pull the weeds with damaging the tall, spindly plants.

• Shake the seed from the flower heads and store the seeds in the paper bag in a cool (60 to 75 degrees F) location.

Remove all weeds and grasses from the planting area. Enrich the planting area with as much as a 3-inch layer of compost worked into the top 3 or 4 inches of soil. Rake the area smooth.

Spread the seeds over the planting area and slightly cover the seeds with a thin layer of soil. It is OK if some of the seeds can still be seen on the surface of the soil. Lightly water the seeds so they will adhere to the compost soil mixture and not blow away. If planting in the fall, they should not need any extra moisture until the next spring or summer when the plants need to be watered regularly. If planting in the spring, do not allow the soil to dry out until the plants are actively growing, then water regularly to keep the soil moist, but not wet.

Crop King Seeds is a Canadian seed bank with a unique history. The company originally started in the early 2000’s, but had to close up shop in 2005 due to the uncertain future of Canadian cannabis laws. After a long hiatus, Crop King Seeds cropped up again – this time in the US, where a few states like Colorado and Washington had recently voted to legalize cannabis. From there, the business grew and grew until the Canadian climate was ready to welcome them back again with open arms.

In the early part of 2013, Crop King Seeds returned home and put down roots at their first physical storefront in Calgary, in the province of Alberta, Canada. They now ship seeds from their main office in Vancouver, as well as selling them through over 100 retail partners that have physical storefronts. With recreational cannabis now legal all throughout Canada, the sky’s the limit as to how far Crop King can grow.

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

• If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
• If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

Understanding Milkweed (Asclepias) Seed & Germinating

Germination: To start Milkweed seed we recommend starting inside, but before this happens Milkweed seeds need to go through a cold stratification period. Cold stratification is very important for the germination and growth of Milkweed. It helps break the seeds natural dormancy cycle. To do this, we recommend placing Milkweed seed in a damp paper towel or damp sand in a zip lock bag and place in your fridge for 3 – 6 weeks (30 days). Place in an area of the fridge, where it won’t get damaged. We taped ours to the bottom of a refrigerator shelf.

Growing Indoors

Planting In Spring: Once the 30 days are complete, it’s time to plant the cold stratified Milkweed (asclepias) seeds. We recommend planting in 2-4” peat pots. Fill peat pots ¾ of the way with seed starting potting soil and gently add water. Water should be able to drain through the peat pots. Once the soil is damp, place 1-2 cold stratified seeds into each pot. To finish, place 1/4 inch of soil on top of the seed.

Planting In Fall: If you’re planting Milkweed seed in the fall, let nature do the cold stratification for you! There is no need to place your seeds in the refrigerator before planting, you can plant seeds directly into the soil after there have been a few frosts in your area. This allows for the seeds to remain dormant for the winter and come up in the early spring. Clear away any existing growth and using your index finger to measure, create 1.5″ holes for each Milkweed seed. We recommend spacing seeds about 4-6” apart. Place a seed in each hole and cover. Water thoroughly.

Watering: Gently water the planted seed to give additional hydration. The best way to water is from the bottom up. Use a flat pan under the peat pots and add a half inch of water to the bottom of the tray. Don’t over water as it can cause fungus. Water every day or every other day as needed, the best way to test the soil dampness is to touch it. If the soil seems dry then add water; if it’s wet, wait for the soil to dry out to water.

Light Requirements: For the next few weeks, make sure the Milkweed is either in a sunny window, in a green house or under a grow light. Milkweed needs lots of sun and warmth to grow. If you’re using a grow light, make sure to lower the bulb closer to the pots or your seedlings may become leggy, as they stretch to the light. In our experiment, this happened to us. Ideally a sturdier stem is better. Cold stratified seeds should germinate and sprout within 10-15 days once planted. In total Milkweed from the day they are cold stratified to growth can take 40 plus days, so be patient!

Other planting options: Place dry seed (not stratified) in seed starting soil and plant in peat pots under a grow light or in a greenhouse to germinate seeds. The success rate for this is low and more difficult to accomplish. If you choose to use this option it can take months for the seeds to germinate.

If you are planting seed outside, we suggest seeding in late fall, and let the Milkweed seed lay on the ground through winter. Milkweed seed will have a long winter of dormancy, so once the sun comes out and the ground warms in the spring, the seeds will germinate on their own.

Transplanting Milkweed (Asclepias) Seedling Outdoors

Where to Plant: Milkweed does well in open areas with full sunlight exposure areas like fields, parks, cultivated gardens, roadsides, highway medians, and road sides. We suggest transplanting Milkweed when the plant is no larger than 3 inches tall. In most cases in transplanting, the Milkweed plant will go though some shock and could lose all its leaves. This happens, don’t panic. The plant is trying to establish its roots and will eventually grow leaves again. This is the main reason we suggest planting seeds in peat pots, because Milkweed roots are very sensitive. Peat Pots breakdown over time in the ground, which allows the milkweed roots to grows without being disrupted. We found this to be the best way to transplant. If you decide to plant in plastic containers, but make sure it’s deep enough for roots to grow. If you receive a plant already grown in plastic, be careful to take out the plant and not disturb the roots.

When to plant: Soil moisture and temperature are very important when growing Milkweed. The best time to plant Milkweed is in early spring after the danger of frost has passed. If you plant seeds late in the spring, the seeds may not grow due to Common Milkweed Field Grown germination time and temperature. Common Milkweed seed doesn’t germinate over 85 degrees.

Caring For Milkweed (Asclepias) Plants

Once your seedling is planted, water it for a few days to get it established, but after that, the plant doesn’t need a lot of supplemental water. Only water if you have an unusual dry spell. Peat pots are nice to use, but you need to be sure there is no top edge above the soil line after transplanting. In dry climates, this will wick away valuable soil moisture. A small 2 1/2″ diameter x 3 in. deep pot is ideal. Asclepias are somewhat finicky native plants. So minimizing the time growing in a pot and transplanting them as young plants is the best approach.

How to Plant Butterfly Weed Seeds

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Spread a 1-inch-thick layer of mulch around each plant. Water weekly to a 2-inch depth during their first summer, then cease supplemental irrigation.

How do I germinate butterfly weed seeds?

Harvest the seed pods of butterfly weed when the pods begin to split. Seeds can be sown directly outdoors in late fall or started indoors.

When sowing seeds outdoors, work up the soil in a protected location in early to mid-November. Scatter the seeds over the prepared seed bed and then cover the seeds with approximately 1/4 inch of soil. The cold, moist conditions over winter improve seed germination. Seedlings should emerge in spring. Carefully transplant the seedlings to their permanent locations when the seedlings are 3 to 4 inches tall.

To start seeds indoors, fill a flat with a commercial germination medium (such as Jiffy Mix). Moisten the medium. Scatter the seeds over the surface of the germination medium and lightly press the seeds into the material. Cover the seeds with an additional 1/4 inch of the germination mix. Carefully moisten the additional material. Slide the flat in a plastic bag and place the bagged flat in the refrigerator. Leave the flat in the refrigerator for 4 to 6 weeks. After 4 to 6 weeks, remove the flat from the refrigerator and place it in an area with a temperature of 70 to 75 degrees Fahrenheit. Seeds should begin to germinate in 3 to 4 weeks. (If no seedlings appear after 4 weeks, place the flat back in the refrigerator for another 4 to 6 weeks and repeat the process.) Take the flat out of the plastic bag as soon as seedlings appear and place the flat under fluorescent lights in a 60 to 65 degree Fahrenheit location. Transplant the seedlings into individual pots when the seedlings are 1 to 2 inches tall. Continue to grow the seedlings indoors under fluorescent lights for several more weeks. Prior to planting outdoors, place the seedlings outdoors in a shady, protected location and then gradually expose the seedlings to longer periods of direct sun. Plant the seedlings in their permanent locations after they have hardened outdoors for 10 to 14 days.
