Cons:

  • Rough leaves for monarch caterpillars, not typically a heavily used host plant
  • hard to transplant because of tap root
  • Aphids can be an issue
  • Difficult to grow in clay soil
  • Takes up to 3 years to really get growing
Milkweed buds are often where you'll find monarch eggs or caterpillars on Ascelpias tuberosa butterfly weed.
Buds are a Tuberosa Delicacy

Tuberosa Growing Tips:

  • Grows well in sandy, well-draining soils
  • Fertilize with organic slow-release fertilizer
  • This can be a difficult choice in the wrong spot. However, it also can take awhile to get going. Give it 3 years to prove it’s worthy for your garden
  • Since tuberosa can be temperamental about growing conditions, try planting in a couple different spots to see where it grows best.
  • Transplant milkweed in early spring or fall for a higher survival rate
  • Cut off pods to stop seeding or
  • Use twist ties or rubber bands to bind pods for seed collection

    Hi Tony, My milkweed plants come back year after year and new plants start from what I have. I have a problem with butterfly weed. It will grow like crazy but then never comes back. I am wondering if this is an annual or perennial. Or am I just doing something wrong, thank you – Kate

    • Tony Gomez says

      July 30 at 7:38 pm

      Hi Kathryn, are you sure you’re actually buying Asclepias tuberosa? Some nurseries use butterfly weed to label tropical milkweed plants…Asclepias curassavica is only a perennial to zone 8 and up.

  2. Mary Ottea says

    Help! My butterfly weed has aphids. What can I use to get rid of aphids and not harm the caterpillars (if I ever get any).

    I just planted these and then read where the leaves and stems could be poisonous to animals. Is this true. I have dogs that like to eat leaves and grass. If this could hurt them they will hit the garbage.

    • Tony Gomez says

      May 19 at 7:48 am

      Hi Barb, our past two dogs have been grass eaters, but never touched any of the 15 different varieties we have planted throughout our yard. Milkweed has a bitter taste and most animals won’t touch it. If you’re concerned, an alternative option is to put fencing around the plants…

  4. Claudia says

    As some people have alluded to, there are substantial concerns with planting tropical milkweed for monarchs. It is more prone to OE, which infects the monarchs, and disrupts the migration of the monarchs. A link to a scientific article describing this is here (Science magazine, no subscription required): http://www.sciencemag.org/news/2015/01/plan-save-monarch-butterflies-backfires

    Thanks for the informative website.

    • Tony Gomez says

      May 5 at 4:43 pm

      Hi Claudia, tropical milkweed is more prone to collecting OE spores in continuous growing regions like Florida and southern California. In other regions it a valuable tool for supporting monarchs in addition to native milkweed. Here’s more info:

      Is Tropical Milkweed Killing Monarchs?

  5. Beth says

    April 29 at 8:33 am

    Can you delete the comment suggesting tropical milkweed as a host plant or at least point out that it should only be used in the south? It’s hurting migration and causing health concerns. I’m trying to combine common milkweed with butterfly weed but I’ve noticed that fireflies house on the common variety. Will that cause my monarchs problems? Should I create a caged house? I was trying to go a natural route. Also, my backyard floods and then dries after receiving 40mph winds. Can swamp milkweed survive the chaos if I plant it near or around arborvitae? Is it invasive? Will it harm my arborvitae?

    • Tony Gomez says

      April 30 at 12:15 pm

      Hi Beth, tropical milkweed is an excellent option for attracting/supporting monarch butterflies and I’d argue that it’s more problematic in continuous growing regions where it collects more OE spores than native milkweed becuase it doesn’t die back. There is no actual data to suggest it’s negatively impacting the migration. We’ve grown it for almost a decade and monarchs are not staying late because of it. They are depending on other environmental cues including wind direction and daylight hours. I’ve never seen (or heard of) any issue with planting common milkweed and butterfly weed together but keep in mind A. syriaca spreads aggressively through underground rhizomes. We raise indoors becuase it’s easier to protect caterpillars from extreme weather conditions and predators.

    I stay in Texas my friend just introduced me to these beautiful plants I have the Butterfly Weed
    Asclepias tuberosa (Yellow) she gave me the plant in a 3 gallon pot
    There were 3 large caterpillars on there when she gave it to me
    I placed it up front of my window where it gets good sun walk out the next day the 3 caterpillars are gone? What did I do wrong? The plant even looks more dried out from just yesterday of her giving it to me? Is it because I have placed it around my other plants? I even bought a plant to place beside it that attracts butterflies lol help! I really love this plant & want to see it grow threw the years in my front little garden

    • Tony Gomez says

      November 30 at 5:40 pm

      Hi Veronica…if they were large enough, they could have crawled away to form a chrysalis. The less happy ending would be that predators found them:

    I planted 2 asclepias tuberosas this spring. They are beautiful and grew really well with lots of flowers.Now that it is the beginning of fall I have a lot of seed pods on them and I don’t know what I am suppose to do with them or how to take care of them to reseed or do I just leave them alone?

    Had a nice butterfly milkweed plant last year, but it didn’t come up this year. So I dug up the area and found good roots, but appears rotten where the plant was. What would cause this? and, can I replant the roots and get them to grow?

    • Tony Gomez says

      June 5 at 7:18 pm

      Hi Mike, perhaps the area was too wet…not well drained soil? Yes, if the root system looks viable, you could try planting it and hopefully it will come back next season.

    • Terry says

      July 18 at 2:46 pm

      Butterflyweed breaks dormancy later than anything else in my garden, so I’ve learned to wait patiently, and in the fall mark where they are so I don’t accidentally dig them up.

      • Mike says

        August 6 at 8:59 pm

        I take a wooden stake, cut it into 3 parts, and stake around the plant so I avoid tilling that particular area in the spring.

  11. Ginger-lyn Summer says

    May 10 at 12:56 pm

    I just bought a butterfly weed plant. I grew them many years ago in my “urban garden”, where they only had about a foot to a foot-and-half patch of grass, with a fence on once side and concrete on the other side. I was planning on planting my new little plant next to my concrete patio, but after reading about the roots am concerned this may not be the best place. It is the best place in terms of sun and not getting mowed over by idiot lawn mowers (I just had my lilies in front decimated the other day). Do you think it would be okay to plant them maybe a couple of inches away from the patio and have them do well there? They will get plenty of sun, although the soil in Ohio is pretty clay-ey (but then, I was in Ohio when I grew them before too). Should I add some compost to the hole I will plant them in to help with the high clay content of he soil? Thank you for any help!

    • Tony Gomez says

      May 10 at 9:36 pm

      Hi Ginger-lyn, it sounds like you have found a good place for your plants. If you’re concerned about soil quality, amending with compost is a good idea.

    April 27 at 10:03 pm

    I recently planted two small butterfly weed (about a foot high) and one has been eaten to the stems by cats (moved them all to the other plant that was untouched and going out to buy more tomorrow). Is the plant that was eaten down a goner or if I cut it down will it come back? I live in Central FL. Unsure what is best route to take with stripped plants. Thanks!

    • Tony Gomez says

      April 28 at 9:29 am

      Mi Michelle, if the milkweed plants have good root systems they should come back. I would give it some time and see what happens…good luck!

    • Veronica says

      April 29 at 1:32 am

      My butterfly weed does not show signs of life (April 29), it shows no signs of spring shoots. Does this plant start in the summer? Or should I be worried about it not looking a bit green.

      Thank you,
      Verónica

      • Tony Gomez says

        April 29 at 3:17 pm

        Hi Veronica, not sure where you’re located but I haven’t seen any of our tuberosa plants coming up yet in Minnesota…they usually take a little longer to emerge than other milkweed species. new shoots will emerge from the ground.

  13. Scott Steffens says

    April 16 at 1:05 pm

    Hi Tony,

    I live in Sacramento, a pretty hot place. I bought Asclepias Tuberosa last October and planted it in my backyard. The foliage died off over the winter. It is now April and I keep waiting to see new growth and I haven’t seen any yet. When should I see new growth on it and is there anything should be doing to get it to start growing again?

    Thanks,
    Scott

    • Tony Gomez says

      April 16 at 9:11 pm

      Hi Scott, I would ask someone with first-hand growing experience in your region (I’m in Minnesota) what their experience is. Check out my western resources page:

      Western Monarch Resources

  14. Bett says

    November 19 at 2:13 pm

    I bought 4 Asclepias Tuberosa plants to add to the milkweed in my yard. I figured the caterpillars would like it since the plants have thinner, more delicate leaves similar to Tropical. However, I have not found a single caterpillar on the plants even though they are nice and bushy now. I’m finding cats on complete stripped Tropical, but none on the Tuberosa. I cut some Tuberosa stems to feed the cats in the castle, but the cats won’t eat it. They will eat literally everything else and leave those leaves alone. They will even eat the leaves from the Giant milkweed tree which are much thicker (and I am assuming harder to eat) but leave the Tuberosa.

    I swear if I hadn’t found caterpillars on the plants when I bought them, I would think that the nursery sold me the wrong plants. I hope the butterflies like the flowers, because the cats sure don’t like the leaves.

    • Tony Gomez says

      November 20 at 4:30 pm

      Hi Bett, in a side by side taste test with other milkweed varieties, it won’t fare well. But if the eggs are laid on it, and the caterpillars haven’t been eating other varieties, they will be fine with it.

      I’m guessing they don’t enjoy the rough, sapless leaves of tuberosa compared to other species. We still have a few tuberosa plants in the garden to give our visitors a variety of options. It’s a good nectar plant too…

  16. Gina says

    September 10 at 4:40 am

    I have switched five caterpillars from one milkweed to another and my babies haven’t moved since. It’s been from about noon yesterday until 5:30 this morning. The first plant was from Home Depot and the second plant which is much more mature is from a nursery. The plants are the same kind but the first one is a much younger plant. I’m devastated. Should I move them back to where they were?

    • Tony Gomez says

      September 11 at 10:03 am

      Hi Gina, I hope the new plants have not been treated with pesticides. If they still aren’t eating I would move them back…good luck!

    • steve lack says

      September 22 at 4:56 pm

      Yes, immediately move them back. The Home Depot plans, virtually ALL of them, are treated with a neonicotinoids. Some plants are labelled, but I’ve seen many labels on the floor as they get knocked off. Its disturbing that even indoor plants are treated this way. I would not trust anything from HD unless they pledge to not do it any more. They have made murmurs of doing so, and have made a few concessions, but its not universal. This would be outright poison for your poor caterpillars.

      • Paula says

        April 11 at 9:10 pm

        Do you think a Home Depot butterfly weed plant would be safe during a second growing season if cut back to the ground the first year?

        • Tony Gomez says

          April 13 at 8:14 am

          it should be fine, or at least much less toxic than when it was treated. if you’re unsure, you can always test with 1-2 caterpillars before feeding more…good luck!

        • Perdidobeacher says

          May 12 at 11:41 am

          Last year was my first go around with monarchs. My good intentions to help preserve the Monarchs by buying tropical from HD was rewarded by getting tons of cats and all of them died in a few days and a few lasted a few weeks before dying off. I blamed predators but eventually realized it was probably pesticides. We cut them back and the second go around ( in the same season) I had no problems at all and had cats well into the fall who were healthy. Hope this helps.

      • Anomonous says

        August 5 at 8:38 pm

        Are you sure because I bought Asclepias tuberosa and it said it would help. Now I am not sure if it is safe. Is it true they put pesticides. Thank you so much

        • Tony Gomez says

          August 6 at 11:50 am

          you can always test the milkweed on one or two caterpillars…not all big box stores have milkweed treated with pesticides, but many still do.

        I have had my butterfly weed in a large pot and it’s in its second year. This year it is now on its second blooming. The first browned out in mid-July and then fresh shoots emerged and is now in full bloom. I take it as a good sign that what looks like a monarch caterpiller is now attached to one of the orange buds. May I transplant the plant when it goes dormant or wait until after the last frost of spring?

    I believe a tuberosa is in my garden. I did not plant it, but it showed up as a volunteer. This is its third summer and has not spread. This summer I bought a Pentas (Pentas lanceolata) from a local garden store. I was told it was butterfly weed. Is this true? Will Monarchs use this as a host plant?

    • Tony Gomez says

      June 19 at 9:18 pm

      Hi Vanessa, you could either try dipping them in rooting hormone powder and direct planting in your garden or put them in a glass of water to see if they’ll start rooting, like is commonly done with tropical milkweed:

    June 15 at 2:36 pm

    I have several A. tuberosa seedlings that I started in late Feb / early March from seed bought from Walmart. I had very good germination both with and without stratification, and good survival so far.
    I noticed yesterday that one of the bigger seedlings is working on a head of bloom buds. I didn’t expect any of them to bloom this year. Should I allow it to bloom, or would it be best to pinch the bloom buds off?

    • Tony Gomez says

      June 15 at 8:48 pm

      Hi Arthur, why would you pinch back the blooms? Enjoy the unexpected surprise!

      • Arthur Dent says

        June 16 at 9:06 am

        Thanks Tony. Most of my growing experience is with carnivorous plants, where when a young plant blooms it is often recommended to pinch off the bloom buds so the plant can put all that energy into growing instead of blooming. In this case I will indeed enjoy the unexpected bonus!

        • Tony Gomez says

          June 19 at 8:54 pm

          Hi Arthur, your tuberosa plant shouldn’t grow that much its first season anyway. If you had two first year flowering plants, I would suggest an experiment.

          • Arthur Dent says

            June 26 at 12:19 pm

            Tony, two more of my first year tuberosa are now putting on bloom buds. I would be interested in your experiment suggestion.

          • Tony Gomez says

            June 26 at 2:00 pm

            Hi Arthur, just try pinching one or two of them back, and leave the other to see the difference in growth habit. Our mature tuberosa plants have two bloom periods and we don’t pinch them back at all.

  26. Marcelle McAfee says

    June 6 at 6:31 pm

    I moved into a new home in San Marcos, CA a few months back and purchased a couple smaller Asclepias curassavica plants (about 12″ tall). I noticed this past weekend that I had a number of monarch caterpillars on them, and now they’ve entirely devoured one plant down to branches only and I’m pretty sure when I get home from work today, the other plant will be entirely eaten. I have at about 10 caterpillars that are about an inch and a half long each. Do you think that they’re now big enough to survive without purchasing more plants (these were $12.99 each… yikes!) or should I purchase more in order to keep them alive? I’m not sure how much more they need to grow before they build their cocoons. Thank you!

      Hi Marcelle, just 1-2 caterpillars can devour an entire milkweed plant so I’m sure they will need more milkweed. good luck!

    I received a packet April 21, 2016 of Pink Butterfly Milkweed Asclepias tuberosa seed at the District meeting of the Montana Federation of Garden Clubs. The package is from Golden autumn The farm.
    I put some seeds in water. I stratified some seeds. More sprouted with the stratified method.
    My question is “What does the sprouting Asclepias tuberosa look like? Some of the seeds have long narrow leaves. Some are more oval. Which one is the A tuberosa?
    Some of the sprouts are now 1 1/4 inch tall and I am planning to set them out in my garden which gets morning sun.
    Do I put both of the starting plants?

      Hi Bonnie, the first set of leaves are more oval (cotyledons) and the true leaves of the plant are narrow. Here’s what a seedling looks like:

    May 31 at 3:42 pm

    We planted three (orange-flower) butterfly weed plants in Central Vermont (zone 4) last summer, in full sun, and they grew pretty large and flowered twice over. A lot of people up here were surprised they’d done so well. In late Sept/October, however, they were seriously attacked by orange aphids, which I tried to hose off as best I could. Pretty soon after the stems seemed to dry out and the plant turned black and fell apart altogether. First frost probably helped too. So I figured they were dead and cut them down to the ground. But in fact they were only dormant, as all three have new growth as of a couple of weeks ago, which is thrilling. So I bought six more (not easy to find, had to go to four nurseries, and they were very pricey) and planted them this past weekend in another location, to see how they fare.

    Anyway, my question is: Can aphids damage the plant, and how can we best get rid of them? I’ve read that some people use insecticidal sprays, but would prefer to avoid, especially since this area of the garden is approximately in the location of our underground water tank.

    • Tony Gomez says

      June 1 at 9:08 am

      Hi Glen, congrats on your returning plants. Aphids are a huge problem in milkweed patches across the country. As your garden becomes more established, you should also start attracting more aphid predators. We now have regular populations of ladybugs and lacewings, and that has prevented serious infestations for the past 5 years. Check out this post for some ideas to help your patch this season:

      10 Ways to Stop Aphids from Taking Over your Milkweed

      PS…large aphid infestations hurt the plants and decrease seed viability…typically, they don’t kill the plant.

        June 3 at 8:16 am

        Thanks for the link, Tony, much appreciated. Good to know that the aphids don’t kill them, even if they do damage, alas. We did notice quite a few ladybugs last summer, the kids loved them, and I’m hoping they’ll return. Thanks again. Glen.

    I had As. tuberosa in my main b-fly garden and it wasn’t doing too well – I think it was being overshadowed by the taller milkweeds. So last year I dug it up, split it into 2 clumps and replanted them into a small plot in my front yard. Oh boy! Was it happy there! It grew a bit taller and I rescued a dozen cats to bring in to my rearing cages. Hope it does as well this season.

    Hi Tony, did you keep records of time into water on heat mat and beginning germination? I’m curious as to approx time from beginning to first seeds sprouting using your water germination method.

    Does it provide a quicker way to germination?

    Mary

    • Tony Gomez says

      March 14 at 5:17 pm

      Hi Mary, it took over a week, but it was cold downstairs and my heat mat wasn’t working…it took me a few days to notice. Once the water warmed up a little bit most of the seeds germinated as you can see from the photo on the page. Again, I did not cold stratify the seeds. Next spring I am going to try soaking some in water for 24 hours like I do with the warm weather milkweed varieties.

  33. Tony Gomez says

    Hi Brian, congrats on your tuberosa seedlings. Fresh incarnata seeds generally have a high germination rate. Have you tried a heated seedling mat to speed things along?

    Tony,
    The 30 day moist stratified seeds of tuberosa germinated very readily in soil the incarnata have not done so yet. Over the past few summers I find a few instar on the tuberosa leaves. Happy almost spring.

    Thanks Tony. The funny thing is, about a month ago I put some of my wild collected tuberosa seeds in a water container to try that method, no sprouts at all yet. Two incarnata seeds out of twelve have sprouted that way, and none of the syriaca.

    March 1 at 11:02 am

    Every year I see “Butterfly Weed” (which I assume to be A. tuberosa) seed packets at Walmart, and always wonder how well they would germinate since the packet instructions make no mention of stratifying the seeds.
    This year I decided to try it and see. I planted 21 seeds in peat pellets in a plastic dome and placed under lights on my growing rack. I did not soak the seeds first, and I do not use a heat mat, took the seeds straight out of the packet. This was this past Saturday, the same day I bought the seeds. Last night, Monday night, I noticed that almost half of the seeds had sprouted already! I never dreamed that I would get such good germination, and so fast. Now I’ll have to grow them out and compare to my wild collected A. tuberosa and the seeds that I bought online, which are now all stratifying in the refrigerator.
    I just thought someone might be interested in my little experiment.
    Tony, do you have any thoughts on why these would work so well without any stratification?

    • Tony Gomez says

      March 2 at 8:30 am

      Hi Arthur, tuberosa is one of the easier seed varieties to start. It can also be started in wet paper towels/coffee filters in a sealed food storage container or in water under grow lights…both without cold stratification. I am currently experimenting with these propagation techniques and tuberosa is responding well.

      Even a decade ago, there wasn’t a lot known about gardening with milkweed. Through all the social networking on the internet, there is a lot of new information coming to light that is blowing old assumptions out of the water. Experiments are good…thanks for sharing your results.

    • Tony Gomez says

      February 1 at 9:16 pm

      Hi Cynthia, I’m in Minnesota. Up here A. tuberosa just dies back to the ground and reemerges next spring. I clear the dead stems and foliage in the spring. Cutting milkweed back allows healthy new growth to emerge for next season. Plants that aren’t cut back can collect OE spores and spread disease to future monarchs. Here’s more info about OE:

    December 31 at 8:58 am

    I started Asclepias tuberosa from seed in seed trays. End of December brings a wonderful germination and I have them under grow lights. Should I keep the plants cold to control growth till my zone 5 garden is ready? I assume that they wouldn’t do well if I planted them out before the last frost.

    • Tony Gomez says

      December 31 at 7:18 pm

      Hi Stacy, if we start native milkweed seeds indoors it would be about 8 weeks before planting outdoors. I’m not sure how that will affect the growth cycle, but it sounds like an interesting experiment. You might also want to try an alternative form of propagation like winter sowing in case you have any issues with these early plants. Let us know what you learn from the experience…thanks!

    I’m looking to make my garden friendly for both butterflies AND honey bees – if I’m trying to appease them both, would this or syriaca be a better choice?

    • Tony Gomez says

      December 29 at 7:12 pm

      Hi Heather, bees are frequent visitors to both types of milkweed but syriaca is typically more attractive to monarchs as both a nectar and host plant. The one advantage to tuberosa is it blooms a bit longer. There are many milkweed varieties to choose from and having 3-4 species planted will attract/support more monarchs and other pollinators.

    Any suggestions? Am in Central NC and this is supposed to be a native for this area.

      Hi Peggy, it’s getting late in the season and tuberosa is past its prime. The only milkweed varieties that stay viable this time of the year are tropical milkweed and other non-native varieties. I would stop fertilizing it and just water it to get it acclimated. Your plants should look much better when they return next spring…

    This is our first year to plant a butterfly garden. We live in a suburb of Chicago. We have many Milkweed plants in our area that grow wild and quite a few that have come up in our yard. We picked an area next to our house and planted butterfly weed and butterfly bushes. There is also Milkweed intermixed. A friend gave me 2 Tuberosa plants – one orange and one yellow. We’ve been very successful attracting Monarch butterflies. Out of all the plants, they seem to prefer the Tuberosa plants. I’ve had as many as 7 Monarch caterpillars on one plant and they have eaten them bare. So far we had 4 pupas. Two have hatched open on Labor Day. 2 pupa were on our Butterfly Bush and the other 2 attached to our brick windowsill. I believe there are more pupa but they are so well hidden, they are hard to see. It is such fun watching the stages of the butterfly.

    I have planted several milkweed plants in Orlando, FL. They are ~4 ft tall but only have leaves on the top 12 inches but yet they are blooming. No leaves on the remainder 3 feet. Is this normal? Should I cut them back to make them bushier? Thanks, Heather

      Hi Nedday, I would cut back the spent blooms after the first flowering period. We didn’t do it this season, but got more blooms because we had caterpillars eating the plants. Our ‘hello yellow’ cultivar was not cut back but it is putting out some new blooms too. Cutting back will probably give you a few extra blooms, but you still might get some without…

    • Tony Gomez says

      July 12 at 1:00 pm

      Hi Susan, I have never cut back our tuberosa plants before. As they have matured the past couple seasons, they are putting up more stalks (and blooms) on their own without extra encouragement. You could always try cutting back one or two plants to see if you notice a difference in growth habit…good luck!

    June 30 at 11:15 am

    Hi Tony,
    I have a Butterfly Weed plant that is several years old. It is a beautiful, full plant with lots of orange flowers every year, at first. I read that it’s suppose to bloom throughout summer but mine only blooms for a short period . It also starts out nice and bushy but by the time the flowers bloom it splits down the middle. Normally I would have divided a plant that looks like this but I am afraid to divide this one. Any suggestions on what I should do to encourage longer bloom time and whether or not to divide it and when? Also I have never seen it produce seed pods. I live in Michigan, if that’s a factor.

    • Tony Gomez says

      July 1 at 12:38 pm

      Hi Sharon, our plants are not mature enough for division so haven’t tried, but we have had a lot of success with transplanting. You might try a fertilizer with a high middle number (phosphorous) to promote blooming. I would try division in early spring when the plant is just starting to put up new growth, or in late summer as it starts to cool. This way, more energy can go into establishing roots instead of foliage. The plant is usually more stressed when it has to support both. Strange that yours has not produced seed pods…we have had pods in both full sun and partial shade. Perhaps the soil needs to be amended? Good luck with your plants!

      • John says

        November 2 at 11:52 am

        strange…but i have 2 two year old milkweed plants that bloomed profusely all summer, yet, produced NO seed pods. tons of pollinators & monarch caterpillars frequent the two, too. last year, they produced an unbelievable amount of seed; so much so i struggled to keep up! sooooooooo, what’s up with THAT?

        • Tony Gomez says

          November 5 at 7:13 pm

          Hi John, the only thing I can think of is that the caterpillars put them behind schedule for seeding by eating down the stems. Our “hello yellow” cultivar had more flowers this season, was definitely visited by pollinators, but also didn’t produce seed…I’ve heard this is more common for that cultivar though.

      Hello Vi, Asclepias tuberosa can be grown in containers. I would suggest about a 14″ pot to start. You may have to transplant. Cutting back the root system might work too if there is little foliage on the plant when you do it. Good luck!

    My Hello Yellow was planted 2 years ago and it’s looking great this year and has really grown -maybe because we had so much spring rain.

I am seeing Monarchs, Black and yellow swallowtails and Painted Ladies so far but no eggs that I can tell. They have a medium tall mounding habit and look really good planted with pink petunias in front of them. I also have lavender planted in the same bed .

      Hi Connie, nice to hear you had success but many gardeners report finding few eggs/cats on tuberosa or being bypassed completely. We grow about 15 types of milkweed now and tuberosa generally has one of the lowest egg/caterpillar counts. My guess is that the coarse, sapless leaves have something to do with it…

      • Craig "The Butterflyman" says

        February 7 at 10:54 am

        Hey Tony ! I hope you’re well. If steaks not available we’ll settle for hamburger. Tropical is the Steak although it’s perennial in only 5% of the country. Big Nursery promotes it because the customer has to buy it every year and it’s easier to produce than tropical . Tuberosa is the milkweed of the future and past. Read its history in the U S and its range. Look for supplies to increase because of the bad mouthing of Tropical.

        • Tony Gomez says

          February 7 at 11:56 am

          Hi Craig, we grow both steak and hamburger, but we live in a region where E. Coli isn’t a major issue so the tropical bashing isn’t as severe 😉 Because monarchs seem hesitant to use tuberosa as a host plant, I wouldn’t depend on it as the future of milkweed. I’m partial to incarnata because it’s a popular host and nectar plant. I realize incarnata isn’t suitable for dry regions, but it grows very well in containers without a taproot, which makes it a good garden plant for all regions.

          As for replenishing wild fields of milkweed in Texas, I’m not sure what the answer is, but I don’t think it’s tropical or tuberosa…

The location got morning sun (not afternoon) and composted manure was mixed into the soil. Curious to see if they will REALLY take off this season. Keep us posted on your new plants…

    Something is eating the leaves of my butterfly weed plants… ? aphids ?
    What should I do about this?

      Hi Clare, if orange oleander aphids are taking over your milkweed they should be visible. If you have an infestation, you can cut off the most affected stems and discard them to cut back on the population for next season since aphids lay eggs in fall. Otherwise, I wouldn’t worry too much about your butterfly weed at this point. Monarchs typically lay eggs on tuberosa earlier in the season.

        I buy ladybugs and release them at the base of the plant and they eat the aphids as fast as they can. (Like little vacuum cleaners)

          Hi Bette, I certainly like to see ladybugs in the garden, but remember that they eat monarch eggs and small caterpillars too, so releasing them in mass would be a last resort for me. Here’s more info about saving more milkweed for monarchs:

        I just planted a beautiful butterfly weed two days ago. Today, the flowers are completely gone and it looks like the leaves on one of the stems are also devoured. I have groundhogs in the areas but I thought that the butterfly weed was resistant to groundhogs. What else might eat the flowers? Thanks.

          Hi Judy: groundhogs, rabbits, deer…it would seem many of these critters have adapted to the ‘poisonous’ cardenolides in milkweed.

          Hi,

          I have previously had the same problem with something eating my Tuberosa plants and I suspected the groundhogs. This year I fenced in my plant with one foot high dollar store fences and so far nothing is eating them. Very happy but still no Monarch eggs. 🙁
          May have to order some caterpillars 🙂

            Hi Ellen, glad to hear the fencing solved your milkweed problem…I hope your season picks up soon!

    Hi Craig, it’s a good nectar plant, and it can be used as a host plant. It’s not usually the preferred host plant though. Another consideration is that tuberosa is a native plant. Even though tropical milkweed is a better host plant, some people refuse to plant it because it’s non-native. My goal is to lay out all the options and let you decide.

    Why the heck do you have Tuberosa on here if it is NOT A GREAT HOST PLANT??
