Tips for Planting and Growing Milkweed Successfully 

by Sam Doll

Milkweeds are hardy, perennial wildflowers found throughout North America. Some species can grow up to six feet tall and they produce beautiful, fragrant flower clusters. Since they’re common ingredients in traditional medicine, their genus name, Asclepias, comes from the Greek god of medicine.

Milkweed has gotten a bad rap over the years. Allergies and perceptions of the wildflower as a weed have caused it to be wiped out throughout large portions of North America.

This is bad news for the Monarch Butterfly. Monarch mothers will only lay their eggs on milkweed plants (genus Asclepias) and, once hatched, their caterpillars exclusively live on and eat the leaves of those same plants. They cannot survive without them.  The prevalence of pesticides has not helped and the loss of milkweed, wildflowers, and other floral resources has devastated the monarch butterfly population. However, by restoring Milkweed to urban and wild landscapes, we can begin the process of saving the Monarch Butterfly! And our Ultimate Milkweed Growing Guide is here to help.

Why all these steps?

Milkweed seed has a high percentage of dormancy, which means many of the seeds won’t germinate without a little special treatment or might need to age for a season. Since we want to make sure you have complete success with our seeds, here are some tips!

Prep:

Milkweed seeds need to be exposed to cold temperatures that normally occur in winter to help break their natural dormancy and begin to soften their hard outer casing. If you are planning to start your Milkweeds indoors, you will need to do this cold stratification yourself.

You can do this by putting your Milkweed seed in a damp paper towel, folding it to fit into a sealed plastic bag, then placing the bag into the refrigerator. Keep it there for 4-6 weeks before planting.

Planting:

Plant your seeds in small 2-4″ peat pots (recommended) or tall plastic pots. Make sure to use ‘seed-starting’ soil or medium. Moisten the soil, place 1-2 seeds into each pot and cover with no more than 1/6″ damp soil or medium.

Place the pots where they can drain. Water gently or fill a tray with 1/2” of water to be absorbed from the bottom of the peat pots. Dump the excess water after absorption.  Water when the top of the soil is dry and be mindful to not overwater.

Milkweed seeds germinate in warm conditions, so place your tray of pots in a warm spot like a sunny window, greenhouse, or under a grow light. Germination usually occurs after 10-15 days for cold-stratified seeds. To encourage sturdy stems, place your grow light bulb close to the soil. Sometimes a small fan blowing gently towards the new seedlings will encourage sturdier stems.

Other planting methods: Plant non-stratified seed into peat pots filled with seed-starting soil or medium. Moisten, and place in a greenhouse or under a grow light. Germination in this scenario might take several months.

If planting outside, seed in late fall. Let the Milkweed seed remain over the winter. This will accomplish the cold-stratification, needed. Germination should occur when the soil warms and the days are longer.

Oh, and while you’re at it, check out our Monarch Rescue Wildflower Mix. It has Butterfly Milkweed and a mix of other wildflower seeds to provide a nectar-rich place for Monarch Butterflies to fuel up and raise their young! Find it here!

Transplanting:

When the danger of frost is past and your plants reach 2-3″ tall, you can transplant outdoors. Choose a location in full sun if possible.

Milkweed produces a long taproot, so take care to not disturb the roots. Plant peat pots so that the top edge of the small pot is underground to avoid drying out. If your Milkweed seedlings were planted in plastic pots, be extremely careful with the roots. Continue to water after planting until plants become established. Once they are established, you can taper off your watering unless the season is extremely dry. The newly planted Milkweed seedlings may lose all their leaves due to transplant shock but should grow them back again.

Congratulations!

You’re now a proud Milkweed parent! Now just sit back and watch the Monarch Butterflies arrive!

What Species of Milkweed is Best For You

By Sam Doll

Monarch Butterflies are amazing North American animals! Their iconic, colorful wings are actually warnings for potential predators. Those spots and strips are big caution signs saying: STOP; I TASTE BAD!

Every year, the Monarchs embark on one of nature’s most astonishing mass migrations. This incredible journey takes four generations and covers over 3000 miles through the United States, Mexico and Canada.

Monarch mothers will only lay their eggs on milkweed plants (genus Asclepias) and, once hatched, their caterpillars exclusively live on and eat the leaves of those same plants. They cannot survive without them.

The problem is that milkweed has gotten a bad rap over the years. Allergies and perceptions of the wildflower as a weed have caused it to be wiped out throughout large portions of North America. The prevalence of pesticides has not helped and the loss of milkweed, wildflowers, and other floral resources has devastated the monarch butterfly’s population.

It’s not without hope, though! Everyone can do their part to help. The most important thing you can do is to plant more milkweed on your property and in your community. This guide to purchasing milkweed seed will help you figure out which species of milkweed is best for you, and you can help Monarch Butterflies!

1.     Common MilkweedClose-up of the Common Milkweed flower.

The Common Milkweed is a hardy perennial with fragrant, terminal blossoms made up of tiny dusty-pink blossoms on hairy stems.  This milkweed is found throughout the Great Plains and is tough enough to tolerate most soil conditions. It does well in soils that are clay, sandy or rocky calcareous (high in calcium carbonate). These conditions occur naturally along stream banks, ponds, lakes, forest margins, and roadsides. Common Milkweed grows 2′ – 6′ tall and like areas with full sun. They bloom from June through September and will germinate between 65° and 85° F.

This milkweed is also a favorite of other butterflies, native bees and hummingbirds. The seeds will grow easily and do well when planted in the fall or when cold-treated for three months prior to planting.  Common Milkweed will spread both through seed normal distribution and as well as through underground shoots. Common milkweed spread readily and may need to be controlled. Common milkweed is particularly good for wetland rehabilitation and as a component in wildlife seed mixtures.

2.     Showy MilkweedThe fluffy seeds of the Showy Milkweed plant.

Similar to the Common Milkweed, this hardy perennial is a favorite of butterflies.  This species has traditionally provided food, medicine and fiber to indigenous peoples. The clusters of star-shaped flowers will range from dark-rose to white. The plant has tall woody stems with milky sap and with alternate, oval leaves that are velvety underneath. Showy Milkweed grows 24” – 36” tall and like areas with full sun. They bloom from May through July and will germinate between 65° and 85° F.

These plants grow well in a variety of locations from prairies and open woodlands to roadsides.  The seeds are very easy to grow and do well when planted in the fall or when cold-treated for three months prior to planting.  Showy Milkweed will spread through seed distribution and underground shoots

3.     Butterfly MilkweedClose-up photo of the blossoms of the Butterflyweed.

Also known as Butterflyweed, this hardy perennial. Unlike their cousins, this species lacks the milky sap that gives milkweed their namesake. The clusters of flowers will range from dark orange to white on tall woody stems with smooth shiny leaves that are velvety underneath.  The blooms begin in May and will last through July. These plants will grow between 12”-24” and perform well in a variety of locations; from prairies and open woodlands to roadsides.

Butterfly Milkweed is only pollinated by large insects. This trait is common among fall wildflowers, many of which depend on specific pollinators to survive. Butterfly Milkweed pollen is contained in a heavy, sticky structure called pollinium. Since these pollinium structures are so large and sticky, only larger insect pollinators can fly with them. There are several nectaries per flower and multiple flowers per bloom, which makes these flowers great pollen and nectar resources

The seeds will grow well when planted in the fall or when cold-treated for three months prior to planting in the Spring. Butterfly Milkweed will spread through seed distribution and underground shoots.

4.     Swamp MilkweedThe pink blossoms of the Swamp Milkweed with a visiting wasp.

 

The Swamp Milkweed is widely distributed across the U.S. and Canada; from Quebec and Maine south to Florida and Texas and west to Nevada and Idaho. This species prefers neutral to slightly acidic soil, although it will tolerate a pH up to 8.0. It has high moisture requirements, and it is usually found in wet habitats such as meadows, riverbanks, pond shores, stream banks, wet woods, swamps, and marshes, although it will also grow in drier areas such as prairies, fields, and roadsides. Swamp milkweed needs full sun or partial shade to flourish.

The plant grows into a two=foot tall perennial with fragrant, terminal blossoms made up of tiny rosy-purple blossoms.  This milkweed prefers average to very moist soils, will tolerate heavy clay soils and is easy to start from seed and deer resistant.  Like most milkweed, Swamp Milkweed seeds are easy to grow and do well when planted in the fall or when cold-treated for three months prior to planting.  Swamp Milkweed will spread through seed distribution and underground shoots.

Like the Common Milkweed, Swamp Milkweed is great for wetland rehabilitation and as a component in wildlife seed mixtures.

 

5.     Bloodflower MilkweedThe varigated orange and yellow blossoms of the Bloodflower Milkweed.

Bloodflower Milkweed, also known as Tropical Milkweed, is winter hardy in zones 9-11 and is easily grown from seed each year as an annual.  It is great for attracting hummingbirds, butterflies and a wide variety of pollinators.  Showy red-orange flowers with yellow hoods in rounded clusters grow on upright stems with medium-green, glossy, pointed leaves.  Attractive foliage and flowers for beds, borders, cottage gardens, meadows and butterfly gardens. It is also a good cut flower. Dried seed pods are attractive in arrangements.  Monarch Butterflies lay their eggs on the leaves and the larvae feed on the plants. Plant in rich, well-drained soil.  These have a longer blooming period than most other milkweeds, ranging from June through October.

This milkweed is not native to North America and can potentially be invasive in warmer climates. If you’re one of our Southern friends, monitor your plantings and keep out of wild lands and ranches and cut the foliage to the ground in the winter to avoid luring Monarchs away from their migratory paths.

*Note that all milkweed contains cardiac glycosides, chemicals that are toxic when eaten. These chemicals, in turn, make the Monarch Butterflies toxic to any would-be predators. Avoid letting livestock and small children eat milkweed and wash any skin that comes in contact with the sap to avoid irritation.

Save the Monarch Butterfly!

Doing Your Part to Save Nature

by Sandy Swegel

The big nature news this week was an article in the New York Times that 2013 is the first year anyone remembers that the monarchs didn’t appear in the central forests of Mexico for the Day of the Dead. It’s part of the cultural tradition there that the annual migration of monarchs to their winter home in the mountains of Mexico represents the souls of the dead.  Last year scientists were worried when only 60 million monarchs came back to Mexico, but this year a paltry 3 million struggled in weeks late.

A primary cause of the monarch’s disappearance is the destruction of milkweed in the Midwest, the monarch’s only food. Native habitat in which milkweed thrives has been destroyed as prairie turns to endless mono-crops of Roundup-drenched fields of corn.  There are other factors such as massive deforestation in Mexico and the transition of prairie land to suburbia. But no milkweed means the monarch starves.

It’s interesting that the New York Times has been a big supporter of the monarch.  This was the third article in the last year in which they have featured the decline of the monarch. They have seen the writing on the wall.

What can you do?  Keep up the usual things you do opposing GMO crops that rely on Roundup to wipe out all native “weeds.”  There’s political action work to reduce the corn subsidies that make Roundup profitable.  But as a gardener, you can plant some milkweed and other native plants that will feed the many native pollinators in dramatic decline.  The monarch might be the prettiest most dramatic victim of our prairie destruction, but there are many others.  Gardeners understand the delicate web of life that depends on native habitat.  Tell your friends.

Stalking the Wild Monarch

Plant Milkweed Now

by Sandy Swegel

It’s Show and Tell time.  It’s time to take the kids or some curious adults outside and prove your superior knowledge of the ways of nature and introduce them to butterfly eggs.  It’s been a good milkweed year in the wild this year. Lots of spring rains followed by warm days have made the perfect home for milkweed plants.  Milkweeds are growing in my garden and along roadsides and ditches.  If milkweed plants are fully grown…mine are in tight bud about to bloom…you can walk up to almost any plant and look under the leaves and find little tiny white monarch butterfly eggs.

Milkweed plants, Asclepias, as you probably know are the ONLY host plant for the monarch butterfly.  The butterfly lays her eggs on the underside of the leaves. The eggs hatch hungry little larvae that chew up the leaves.
The larvae get big and fat and eventually form pupae, also on the underneath side of a milkweed plant.
Finally, “ta-da” a monarch butterfly emerges.
I have two favorite kinds of milkweed plants in my garden.  The “showy milkweed” Asclepias speciosa with the big pink seed head you’ve seen in fields, and “Butterfly weed” Asclepias tuberosa which is my favorite because it’s bright orange and looks good in the dry August garden next to the Black-eyed Susans.  It also makes a great picture to see a Monarch butterfly on one of the orange flowers.

Monarchs are happy to choose either of these two “milkweeds” or any of the other more than 100 different species of milkweeds around the world. So you can pick the flower you like and grow it in your own garden. Grow it and the monarchs WILL come.  I’ve had good luck with fall or winter direct sowing of the seeds that easily grow into blooming plants the next year.  After that, they reseed themselves gently.
