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.
How quickly does butterfly weed grow?
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 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.
Can you grow butterfly weed seeds?
Although butterfly weed is easy to grow from seed, many gardeners prefer to replicate through root cuttings because seeds can take two to three years to mature into flowering plants.
Does milkweed flower the first year?
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.
Is butterfly weed an annual or perennial?
Use as a cut flower: Butterfly weed creates a lovely cut flower. Perennial garden, strong color, attractive blooms, showy, long-lived
Where should I plant milkweed?
Milkweed is an essential part of the monarch butterfly’s life cycle. The only plant that monarch caterpillars consume is this one. Before eating the plant’s leaves, these caterpillars hatch from eggs laid on the plant.
However, not just any milkweed will suffice. The goal is to plant milkweed that is natural to your area.
What is the explanation for this? The health of monarch butterflies is jeopardized when non-native milkweed varieties are planted. Non-native tropical milkweed survives the winter in many regions, allowing ophryocystis elektroscirrha (OE), a parasite found on monarch butterflies and milkweed, to reach lethal levels. The parasite, on the other hand, dies with the plant in the winter with native milkweed, ensuring that new milkweed grows with reduced risk of the parasite when monarch butterflies return in the spring.

How do you seed butterfly milkweed?
Milkweed seed can be directly planted in the ground or started indoors. Milkweed seeds can be sown by sprinkling them 1/4-1/2 inch apart on the soil surface, then covering them with another 1/4 inch of earth. After planting, water the area often until the plants have established themselves. Before planting, several species must be vernalized (cold treated). After the threat of frost has gone, vernalized seeds can be planted in the spring. Non-vernalized seeds can be planted in the fall, and the cold treatment will be provided by nature. Further advice, information on vernalization, and directions for beginning milkweed seeds indoors can be found in Monarch Watch’s milkweed propagation guide. Chip can also be heard from in our Monarch Conservation Webinar: Growing Milkweed for Monarch Conservation (scroll down to May 2016).
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, however, is not the case.
