Butterfly bush (Buddleja spp.) and butterfly weed (Asclepias tuberosa) are two different plants with similar popular names. Butterfly bush can be found in USDA plant hardiness zones 5 through 9, depending on the cultivar, whereas butterfly weed can be found in USDA zones 3 through 9. Butterfly weed is native to the eastern United States, although butterfly bush (Buddleja davidii), which is more widely observed, is considered invasive in many locations.
What is another name for butterfly weed?
Butterfly weed (Asclepias tuberosa), also known as pleurisy root, butterfly milkweed, or orange milkweed, is a sturdy rough-haired perennial with long roots that grows in North America’s dogbane family (Apocynaceae). The linear, alternately arranged leaves grow up to 1 metre (3 feet) tall on an erect, somewhat branched stem. It has large clusters of bright orange blooms in midsummer, which are very attractive to butterflies.
Is butterfly weed and butterfly milkweed the same thing?
Butterfly weed is a milkweed family member (Asclepiadaceae). The genus Asclepias is named after Asklepios, the Greek deity of medicine. Tuberose refers to the tuberous (knobby and swellinged) roots of the plant.
Butterfly weed thrives in dry open areas and is abundant in the Midwest and Great Plains prairies and grasslands. This lovely native wildflower can be found from Maine to South Dakota, as well as the desert southwest of the United States and Florida.
Native Americans gathered fibers from the dried stems, which were woven into ropes and used to make fabric. Many tribes ate different sections of the butterfly weed. The dried leaves of butterflyweed and skunk cabbage were used to make a tea to treat chest inflammations in colonial America, earning butterfly weed the nickname pleurisy root. Until 1936, pleurisy root was included in the American Pharmacopoeia and the National Formulary.
Butterfly weed is a multi-stemmed perennial forb with a gritty texture. The stems are hairy and straight. The leaves are simple and alternating. Unlike other milkweed species, butterfly weed contains a watery translucent sap rather than the thick milky fluid found in other milkweed species. The inflorescence is made up of several individual blooms and is slightly rounded to flat. The flower is made up of five petals pointing down and a crown of five upright hoods. The fruit is a pod containing a tuft of silky white hairs on each brown seed. Many a youngster and adult have delighted in pulling the seeds from a mature, opened pod and letting them flutter elegantly in the breeze.
Butterfly weed can be found in formal garden borders as well as meadow and prairie gardens. Because of its dense woody taproot, this wildflower is difficult to transplant. It is simple to grow from seed. Collect theseed as soon as the pods start to open. A three-month cold stratification period is required for butterfly weed seed. As a result, it is advisable to plant the seeds in the autumn so that they can germinate readily the following spring.
What is butterfly weed used for?
Although there has been little evidence to support these traditional applications, Asclepias tuberosa, often known as pleurisy root or butterfly weed, was most typically used to cure asthma and bronchitis.
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.
Do Monarchs eat butterfly weed?
While many butterflies require certain host plants to grow their young (a list of other butterfly host plants may be found here), no butterfly is more important to our collective psyche than the monarch butterfly. Monarch butterfly numbers have plummeted in recent decades, and an increasing number of home gardeners want to help by planting a monarch butterfly host plant in their yard.
Monarch butterflies evolved with milkweeds, and as a result, their caterpillars developed a unique adaption that allows them to feed on a plant that few other insects can. Cardenolides are poisonous chemicals found in the latex-based sap produced by milkweed plants. With the exception of a few species, most other insects are unable to metabolize these toxins, which either kills them or causes them to avoid them altogether owing to their unpleasant taste. However, monarch caterpillars absorb these toxins while feeding on milkweed leaves, making the caterpillars themselves poisonous to predators. The poisons contained in the monarch butterfly host plant actually aid to protect the caterpillars and adult butterflies against predators such as birds and other insects.
Here’s a video of Jessica Walliser finding little monarch caterpillars on milkweed in her own backyard.
Which milkweed is best for monarchs?
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.
Are butterfly weeds invasive?
Milkweed, also known as asclepias, is native to North America, and one of them, Asclepias tuberosa, has been named Perennial Plant of the Year by the Perennial Plant Association this year. This plant, sometimes known as butterfly weed or butterfly milkweed, has bright orange flowers that attract a variety of butterflies and bees with nectar and pollen. Butterfly weed’s leaf isn’t a favorite meal of monarch caterpillars, but it can help them survive. This drought-tolerant plant prefers a dry, sunny environment and is hardy in Zones 3 to 9.
Upright stems with clusters of bright orange flowers contrast attractively with the shiny green leaves of butterfly weed. Unlike other members of the genus, the stem sap is not milky. This milkweed is not invasive since it does not spread by runners like common milkweed (Asclepias syriaca). Although deer are not attracted to butterfly weed, aphids can be an issue in gardens and greenhouses.
This plant is expected to be in great demand in the next years. Butterfly weed blooms readily the first year after seeding, but there are a few crucial elements to remember if you want to grow it professionally.
This species displays some of the most extreme photoperiod reactions we’ve ever seen. It’s an obligatory long-day plant, which means it has to flower during long days. When grown at an average of 68° F, plants develop quickly under photoperiods of 14 hours or more, and begin flowering about eight to nine weeks after transplant. Plants that are exposed to photoperiods of 12 hours or less, on the other hand, die dormant after a few days (Figure 1, pictured above). Leaves droop, shoot growth appears to stop, and existing flower buds may suffocate (Figure 2). Unfortunately, simply reverting to longer days will not return the plants to active growth. A nine-week or longer cold treatment is required to break this dormancy; in our testing, all dormant plants treated to 41° F for 15 weeks bloomed.
It is critical to provide long days to plants in order to keep them actively growing. We propose at least 16 hours of daylight or four hours of night disruption illumination. A minimum intensity of 2 molm2s1 should be delivered by photoperiodic illumination. Use incandescent lights or LED bulbs intended to control blooming that emit both red and far-red radiation. Maintain these extended photoperiods for plants until natural daylengths reach at least 14 hours.
Butterfly weed has a huge tap root, making transplanting or dividing established plants difficult. It’s critical to utilize a well-drained medium in container production, so consider adding more perlite to a standard peat+perlite mix. During production and cold treatments, be careful not to over-water. The taproot attracts fungus gnat larvae, so keep an eye on the roots if your plants aren’t doing well.
Butterfly weed can grow up to 3 feet tall in the wild, but in container production, our plants were only 12 to 18 inches tall when they first bloomed. Sprays of daminozide (e.g., B-Nine, Dazide), paclobutrazol (e.g., Piccolo, Bonzi), and uniconazole (e.g., Piccolo, Bonzi) are apparently helpful for height management (e.g., Sumagic, Concise). To help fill out containers, use many plugs per pot or squeeze seedlings soon after transplant.
Does butterfly weed rebloom?
During the spring and summer, butterfly weed (Asclepias tuberosa) develops green foliage and clusters of little red, orange, or yellow flowers. Plant hardiness zones 4 through 10 according to the US Department of Agriculture. The plant dies back each winter, but if correctly clipped, it reappears each year from its perennial root system. If consumed, all components of the butterfly weed are poisonous.
