Butterfly milkweed is a herbaceous perennial that blooms in vivid orange or yellow umbels (spherical, flat-topped clusters) at the ends of branched stems.
Milkweed is difficult to transplant due to its deep taproot and is best started from seed. The lengthy blooming masses of blooms make the work worthwhile once established. Because milkweed is slow to sprout in the spring and might be damaged when planting or working in landscaped areas, keep track of where you plant it.
Plant butterfly milkweed in full sun on poor, dry soil. While drought tolerant, irrigation will help to prolong flowering. Because the core taproot of butterfly milkweed is prone to rot, it should not be planted in poorly drained or damp soils. For moist locations, swamp milkweed (A. incarnata) is a preferable alternative. Butterfly milkweed may grow in full sun or moderate shade, but it produces fewer flowers in low light.
Self-seeding is easy for mature plants, but seedlings might take up to three years to grow in the landscape. Remove seedpods before they dry and split to prevent self-seeding.
Can you plant milkweed in shade?
Despite its unappealing moniker, swamp milkweed (Asclepias incarnate) is a beauty and one of the easiest milkweeds to grow. However it is commonly found in moist areas, such as along riverbanks or in low spots in meadows, it may survive a surprising range of soil types, though it may require extra watering in drier areas.
Swamp milkweed can be found in nearly every state east of the Rockies, from Northern Canada to Florida. Swamp milkweed can reach a height of 3′ to 4′ and forms tiny colonies under the right conditions. Although it likes full sun, it is one of the shade-tolerant milkweeds and may tolerate moderate shade. The delicate pink, softly perfumed flowers are huge and spectacular, and monarchs love the lance-shaped leaves. When both swamp milkweed and butterfly weed are available, monarch butterflies appear to favor the leaves of swamp milkweed.
Where to plant:
Milkweeds, for the most part, demand full sun (at least 6 to 8 hours a day). Because they rapidly self-seed, plant them in an area of the garden where you can better control their expansion, such as at the back of the border or in a corner. A wind-sheltered location will also help to restrict the distribution of seeds while also offering a more welcoming environment for butterflies. It’s worth noting that milkweed plants have a taproot and are difficult to transplant.
When to plant:
If you’re starting from seed, sow the seeds outside in the fall to give them the time they need to stratify (be exposed to cold, damp conditions) and germinate in the spring, resulting in a good show of flowers the following summer. If you buy starting plants, wait until the threat of frost has passed before planting them in the spring.
Soil:
Milkweed’s preferred soil type is often determined by its natural habitat. The majority of cultivars are fairly forgiving and will thrive in regular garden soil. Swamp milkweed, on the other hand, is an exception, requiring damp, humus-rich soil.
How to plant:
Plant milkweed seeds in a smooth, clump-free soil bed worked to a fine consistency with a rake or rototiller to guarantee successful germination. Compact the seeds into the soil after they’ve been sown (but don’t cover them) to ensure adequate soil-to-seed contact. Maintain a wet planting bed until the seedlings have established themselves. Thin out any plants that are too close together as your plants grow, so they don’t compete for sunlight and soil nutrients.
Spacing:
Plant milkweed in groups of six or more to attract swarms of monarch butterflies to your garden, spacing plants or thinning seedlings to about 6 to 24 inches apart, depending on the type. “Monarch butterflies are excellent at locating milkweed plants, and the more you have in your yard, the more likely they are to find it and lay their eggs all over it.” “Plant as many plants as you have room for,” Kelly Ballard of Joyful Butterfly, a butterfly plant and seed dealer, advises.
Propagating:
Many milkweed species may be cultivated easily from root or rhizome cuttings, as well as from seed. When the plant is dormant and has more energy reserves, take the cuttings in late fall or early spring. When the weather warms up, new sprouts will emerge from the cuttings, and they will often produce flowers the first year.
Where do you plant butterfly weed?
Butterfly weeds are milkweed cousins with towering, clumping perennials that grow 12 to 36 inches in height (31-91 cm.). The flowers are borne atop fuzzy, green stalks with lovely lance-shaped leaves. Butterfly weed spreads through seeds that are discharged from huge pods in the early autumn.
Butterfly weed thrives in a wide range of habitats, including open forests, prairies, dry fields, meadows, and roadside ditches. Butterfly weed looks fantastic in wildflower meadows, borders, rock gardens, and mass plantings in the garden.
Why is my butterfly weed not blooming?
Milkweed species have varied growth tactics, so it all relies on which one you have. Milkweed, in general, does not flower in its first year of growth since it is concentrating its efforts on developing a strong root system. Milkweed may not flower if there is too much nitrogen in the soil, so don’t fertilize it. Finally, if the plant is stressed, such as by drought or severe heat, milkweed may not blossom. Fortunately, monarch butterflies will deposit their eggs on milkweed even if it isn’t in bloom. Because the caterpillars consume the plant’s leaves, your milkweed can still serve as a host plant even if it doesn’t have flowers. Milkweed can also expand by its root system (depending on the species), thus even if it doesn’t flower or go to seed, the plant can spread that way.
Which milkweed is best for monarch butterflies?
Monarch caterpillars solely eat the leaves of milkweed, which is the only plant that this renowned butterfly species feeds on. As a result, milkweed is essential for monarch butterfly survival. They won’t be able to finish their life cycle without it, and their populations will dwindle.
Indeed, milkweed destruction in agricultural areas, as well as urban and suburban environments, is one of the key reasons monarch butterflies are in trouble today.
Plant Milkweed
The good news is that planting milkweed is one of the most straightforward ways that everyone of us can help monarch butterflies. There are many dozen species of this wildflower native to North America, therefore no matter where you reside, you will find at least one milkweed species.
It’s always better to plant milkweed species native to your area. To add to your garden or any landscape in your town, you can harvest your own seed or purchase seed or plants. Three species, common milkweed (Asclepias syriaca), swamp milkweed (A. incarnata), and butterflyweed (Asclepias syriaca), have particularly extensive ranges and are good choices in most regions (A. tuberosa). The latter two are exceedingly decorative and generally available through the nursery trade.
Tropical milkweed, which may be found in many retail nurseries, is not native to the United States. It has, however, become naturalized in the Southeastern United States. Its long bloom time is being discovered to have certain negative consequences on monarch migration and to be a source of disease propagation among monarch populations, according to science. If you have tropical milkweed in your yard, it’s a good idea to prune it down in the winter to help monarch butterflies to migrate to their natural wintering grounds.
Is butterfly milkweed invasive?
If you want to construct a butterfly garden, milkweed is a popular choice. This abundant plant provides food for butterflies and pollinators, particularly monarch butterflies, whose larvae eat only milkweed. The wrong type of milkweed plant, on the other hand, can be invasive and soon take over your garden.
You’ll be enjoying butterflies in your new pollinator garden in no time if you learn a few essential basics about which milkweed plants work best.
Monarch butterflies have a one-of-a-kind relationship with milkweed plants, feeding on their nectar and then laying their eggs on them so that the larvae can feed on the plant as well.
Common milkweed can be found in fields and abandoned areas along the roadside all over the state. That, on the other hand, is not the milkweed you want to grow!
The common milkweed is a very aggressive and invasive plant that will quickly take over your butterfly garden.
Fortunately, there are a number of non-invasive options that benefit butterflies and pollinators. The idea is to match the milkweed plant to the circumstances in your garden. There are varieties that thrive in the shade, the sun, the dry, and the wetter environments. Butterfly weed, purple milkweed, swamp milkweed, and white-flowered milkweed are other milkweed plants to try.
Purple milkweed is a good choice for a butterfly garden in a sunny, dry location. The swamp milkweed, on the other hand, prefers the opposite: a moist, shady environment.
Butterfly weed, also known as asclepias tuberosa, can be found in your local garden center or nursery for added color. This plant produces orange or yellow flowers and makes a lovely perennial for your butterfly garden. The whorled milkweed, on the other hand, is a white-flowered milkweed that prefers to dry in the shade.
Grow the milkweed plants in clusters if you have the space. Monarchs and pollinators will be able to feed and lay their eggs there as a result of this. The larvae will then hatch, grow into caterpillars, and convert into additional butterflies, which you will be able to enjoy throughout the summer!
Where is the best place to plant milkweed?
Milkweed plants in their early stages require a lot of diffuse light to thrive. Plant in a position that receives plenty of direct sunlight.
- Swamp Milkweed, as its name suggests, thrives in moist environments, making it ideal for wet meadows and rain gardens.
- Tropical Milkweed thrives in hot, humid climates and can be cultivated as an annual in the northern states.
Milkweed prefers not to be transferred since it has enormous, deep root systems.
- Butterfly Weed, Whorled Milkweed, and Common Milkweed should be planted 18″ apart.
- Swamp Milkweed grows to form clumps up to 36″ across when it matures. Plant Swamp Milkweed and its cultivars between 30″ and 36″ apart, or plant them closer and thin them down as they grow in.
Milkweed plants can be sown in the spring or the fall. Your milkweed plants will most likely be dormant when they arrive in the spring, with no green leaves above the soil level. This is quite normal. All of your milkweed’s energy is being spent on creating a robust root system at this point in its development. After you plant your milkweed, you should notice it ‘wake up’ as the earth warms and begin to produce leaves milkweed is sometimes slower to emerge from hibernation than other perennials in your garden. While they are dormant, be careful not to overwater them.
Planting in the fall allows your plants to establish themselves before the winter. This perennial plant will return in late April in locations with cold winters.
Growing Milkweed from Seed: The easiest approach to grow milkweed from seed is to follow Mother Nature’s lead and plant them in the fall. If you truly want to start your seeds in the spring, you’ll need to use cold stratification to break their dormancy, which we discuss in our guide to beginning milkweed from seed.
Where is the best place to find milkweed?
Milkweed plants are perennials, which means they live for more than one year and sprout from both rootstock and seeds in the spring. As a result, milkweed will grow in the same general area year after year, albeit the precise site may change. Milkweed can be found in disturbed regions and areas with native landscaping. Check local parks, natural reserves, alleys and sidewalk boulevards, rain gardens, prairie, and (safely) roadside locations, for example. Milkweed used to be prevalent in the Midwest’s prairies, and later within and beside agricultural fields. Their populations have plummeted, however, as a result of habitat loss caused by shifting land use practices. Visit the Biota of North America Program’s distribution maps, the Monarch Watch’s milkweed profiles page, and the Monarch Joint Venture’s Plant Milkweed for Monarchs pdf to learn more about the milkweed species local to your area and where to find them. However, planting milkweed in your own garden may be the most convenient method to discover it! It’s extremely crucial to plant more milkweed right now to assist monarch butterflies recover. When feasible, we recommend planting milkweed species native to your area, as they are most suited to your climate and require the least amount of maintenance. To find seeds in your state, use The Xerces Society’s Milkweed Seed Finder. Download MJV’s Gardening for Monarchs pdf for a quick guide on planting milkweed in your garden. The Monarch Watch’s Growing Milkweeds page has a detailed guide to growing milkweed.
Does milkweed come back every year?
Plant milkweeds that are natural to your area whenever possible. Perennials, or plants that come back year after year, are native milkweeds. Their aerial portions (flower, leaves, and stem) die back in the winter, but their rootstock survives.
Can I grow butterfly weed in pots?
Native to the area, it attracts hummingbirds and other beneficial insects, is drought tolerant, and deer resistant.
This native isn’t as tall as the butterfly bush, but it’s just as good at attracting winged visitors like butterflies, ladybugs, and beneficial insects to the garden. The Monarch butterfly, in particular, enjoys it. Butterfly weed is also more hardy and adaptable to a wider range of soils, making it a viable alternative to butterfly bush if you’re having trouble cultivating it effectively. Don’t give up hope since the plant takes a long time to emerge in the spring. When other plants surrounding it are fully leafed out, my butterfly weed will often just begin to grow. However, it swiftly makes up for lost time by growing to be 4 feet tall and wide and blooming with vividly colorful blooms. It has minimal issues after it has grown.
Butterfly weed can be found all across New England. Sow seeds 6 to 8 weeks before your final frost date in peat pots, thinning to one plant per pot. Alternatively, plant locally acquired plants in full sun in full sun on compost-amended, well-drained soil in the spring after the risk of frost has passed, or in the summer after the danger of frost has passed. One thing that butterfly weed will not tolerate is poor soil drainage. Plants should be spaced 2 to 3 feet apart. Butterfly weed has a taproot, making it difficult to relocate once established.
During the first year, keep the plants properly hydrated and fertilize once with compost in the spring. Because butterfly weed grows slowly at first in our chilly soils, make a note of where you planted it so you don’t dig it up when planting annuals and perennials in the spring.
To encourage greater blossoming and reduce self-sowing, deadhead wasted blossoms. Each spring, weed out self-sown seedlings. Pruning the plant should be done with caution because the stems contain a milky liquid that can irritate your skin. After a frost, cut the plant back to the ground and compost it. Once planted in the garden, it requires minimal maintenance and is drought tolerant. Aphids can be a nuisance at times, but they are readily handled using insecticidal soap sprays. Butterfly weed plants are resistant to Monarch butterfly caterpillar harm. You won’t have any gorgeous butterflies if you spray to destroy them.
Plant butterfly weed in a perennial garden near a window or deck where you can see butterflies. Butterfly weed has bright, intense blossom colors, so combine it with complementary colored perennials like Russian sage, coneflowers, and decorative grasses in the garden. It can also be used to make arrangements in the cut flower garden.
The hardy, species version’s natural blossom color is orange, and it’s often sold simply as Ascelpias tuberosa. A yellow flowered variant is called “Hollow Yellow.” The flowers on “Cinderella” are pinkish-red in color. Plants in the “Gay Butterflies Mix” are red, orange, and yellow in color.
