When the seed pods of butterfly weed begin to split, harvest them. In the late fall, seeds can be sown immediately outdoors or begun indoors.
In early to mid-November, build up the soil in a protected spot before spreading seeds outside.
Cover the seeds with about 1/4 inch of dirt after scattering them over the prepared seed bed.
Seed germination is aided by the cold, damp conditions of winter.
In the spring, seedlings should sprout.
When the seedlings are 3 to 4 inches tall, carefully move them to their permanent places.
Fill a flat with commercial germination material to start seeds inside (such as Jiffy Mix).
The medium should be moistened.
Scatter the seeds on the germination medium’s surface and lightly push them into the substance.
Add another 1/4 inch of germination mix on top of the seeds.
Moisten the additional material with care.
Place the bundled flat in the refrigerator after sliding it into a plastic bag.
Refrigerate the flat for a period of 4 to 6 weeks.
Remove the flat from the refrigerator after 4 to 6 weeks and set it in a room with a temperature of 70 to 75 degrees Fahrenheit.
In 3 to 4 weeks, the seeds should start to germinate.
(If no seedlings appear after four weeks, refrigerate the flat for another four to six weeks and continue the process.)
As soon as seedlings appear, remove the flat from the plastic bag and place it under fluorescent lights in a 60 to 65 degree Fahrenheit environment.
When the seedlings are 1 to 2 inches tall, transplant them into individual pots.
Continue to develop the seedlings indoors for a few more weeks under fluorescent lights.
Place the seedlings in a dark, protected spot outside before planting, then gradually expose the seedlings to greater periods of direct sun.
After the seedlings have been hardened off for 10 to 14 days outside, plant them in their permanent positions.
Will butterfly weed bloom first year from seed?
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.
How do you germinate a butterfly seed?
Butterfly bush can be started from seed indoors and transferred outside after the first frost.
- Using a seed starting kit, sow butterfly bush seeds indoors 8-10 weeks before the last spring frost date.
- Provide lots of light on a sunny windowsill as soon as seedlings emerge, or grow seedlings 3-4 inches under fluorescent plant lights turned on 16 hours per day and off for 8 hours at night. As the plants grow taller, increase the light intensity. Incandescent bulbs will not work since they will become too hot throughout the operation. Most plants need darkness to flourish, so don’t leave the lights on for more than 24 hours.
- Seedlings don’t require much fertilizer, so start feeding them when they’re 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant meal) and follow the manufacturer’s instructions.
- If you’re growing in small cells, you may need to move seedlings to 3 or 4 inch pots once they’ve developed at least two pairs of genuine leaves before transplanting to the garden to give them enough room to develop strong roots.
- Seedling plants must be “hardened off” before being planted in the garden. Move young seedlings to a covered spot outside for a week to acclimate them to outdoor conditions. At first, make sure they’re protected from the wind and the sun. If frost is forecast for the night, cover or bring containers inside, then return them to their original location in the morning. The plant’s cell structure is toughened during the hardening off process, which lowers transplant shock and scorching.
- Turn the soil under to a depth of 6-12 inches, remove any debris, and carefully rake as level as possible to prepare the bed.
- Organic matter (leaf mold, compost, well-rotted manure) is beneficial to all gardens and is especially important in newly built neighborhoods.
- To encourage excellent root growth, unpot the plant and gently loosen the root ball with your hands.
- Place the root ball’s top at the same level as the surrounding soil. Fill to the top of the root ball with soil. With your hand, firmly press the earth down.
- To conserve water and reduce weeds, water well and add a light mulch layer (1-2 inches) on top of the soil.
How do you grow butterfly weed roots?
a hole that is as least twice the width and depth of the bare-root division, which resembles a cylindrical carrot Buds projecting from the crown, which is the top, can be differentiated by ancient growth or protruding buds. Place this ‘carrot straight up in the hole and cover with dirt so that the crown is covered by no more than 1″ of soil.
How do you collect butterfly bush seeds?
The importance of timing cannot be overstated. Before the seed pods entirely dry out but before they crack open, collect the wasted blossoms. To check that the seeds are mature and viable, make sure the entire bloom has turned brown. After collecting the spent blossoms, bring them inside and set them on a paper plate in a draft-free area to dry entirely. When the seed pods are completely dry, they will be spread open to resemble small brown flowers (pictured above). At this stage, all you have to do is gently tap the dried bloom over the paper plate. The seeds will fall out readily.
You can collect seeds without removing the wasted bloom if the seed pods have already split apart. Attempting to remove the flowers after the pods have already opened will almost certainly result in the loss of all the seeds. Simply place a container or paper plate underneath the dried flower and tap it. Do this on a windless day if possible.
Should I remove seed pods from butterfly weed?
The dead blooms are removed, which hinders seed production and stimulates the butterfly weed to grow additional flowers. If you don’t want the butterfly weed to self-seed or just want to improve the aesthetic of your garden, prune off the seed pods in late fall or early winter.
Does butterfly weed have a tap root?
AMES, Iowa AMES, Iowa When the weather is frigid outside, it’s the ideal time to start thinking about spring plants. Butterfly weed, a lovely, low-maintenance perennial, should be included in your designs if you want to add significant beauty and value to your lawn. Specific growing processes should be followed for maximum development and beauty.
Horticulturists from Iowa State University Extension and Outreach offer advice on how to deal with butterfly weed.
What would be a good planting site for butterfly weed?
The milkweed family includes the butterfly weed (Asclepias tuberosa). From July to September, the plants grow two to three feet tall and produce flat-topped clusters of bright orange blooms. The common name comes from the fact that their blossoms attract a variety of butterfly species.
Butterfly weed is a low-maintenance, long-lived perennial that is easy to grow. It thrives in direct sunlight. Plants need at least six hours of direct sunlight each day. Plants thrive in a variety of soils. However, proper soil drainage is essential. The butterfly weed has good heat and drought tolerance once established. Transplanting the butterfly weed is difficult because of its extensive taproot. Choose a planting location with care and don’t disrupt it. In addition, the butterfly weed emerges gradually in the spring. Mark the planting spot and don’t cultivate in the area until the plant emerges to avoid harm.
While most butterfly weeds have bright orange flowers, the ‘Gay Butterflies’ variety contains a few plants with yellow or red flowers. Yellow blooms characterize the cultivar ‘Hello Yellow.’
Can the butterfly weed be divided?
The taproot of the butterfly weed is quite lengthy. Division is difficult and not recommended because to the lengthy taproot. Seeds are the most prevalent method of propagation for butterfly weed.

Do butterfly bushes drop seeds?
Growing seeds is one way to propagate butterfly bush. Butterfly bushes can be grown from seed, however cuttings are usually faster and easier to spread. Pre-chilling seeds for up to four weeks before sowing is required.
Butterfly bush seeds just need to be gently covered with soil because they require a lot of light to germinate. Keep the seeds moist once they’ve been planted. Be patient as they should germinate after a few months.
Is butterfly weed hard to grow?
Butterfly weed requires relatively little work to grow. The plant thrives in broad sunlight and poor, dry, sandy, or gravelly soil with a slightly acidic or neutral pH, and is suited for growing in USDA plant hardiness zones 3 through 9.
Butterfly weed plants are easy to establish from seed, although blooms may take two or three years to appear. Butterfly weed is drought tolerant once planted and flowers consistently from year to year. Keep in mind that butterfly weed produces long, strong roots that make transplanting difficult, so put it in a permanent location in the garden.
