One of my all time favorite flowers and I don't usually prefer orange flowers. Just a bright happy ray of sunshine in the garden. If you have sandy soil, this is your friend. Thrives in sun and sandy loam. No fertilizer, no supplemental watering. Monarch caterpillars all over them, so many they sometimes eat the plants nearly leafless but they still come back the next spring! Bees and butterflies love the flowers. Multiply every year by seed. I plant the seedlings everywhere sandy and sunny. They look amazing with blue flowers like nepeta and with grasses. Last plant to come up in spring... don't forget where you planted them.

Sorry I can't find how to delete a post, but just found out that the plants I have are Asclepias Curassavica, not Asclepias Tuberosa.

This plant is a 10 out of 10. I've started Asclepias tuberosa from seed the past few years and have had nothing but success from them. I have 12+ now, and plan on at least doubling that number this year. They need dry to average soil, and a decent amount of sun. It seems to be a 50/50 chance on whether or not they'll bloom the first year. This plant is easy to keep control of. It doesn't spread underground the way other milkweeds do. The only way this plant spreads is by seed, and that can be easily maintained. The seedpods take about three months to fully develop, so you have plenty of time to cut them off if you choose to. You can also keep them on and collect the seeds when they ripen. This plant also has the brightest orange flowers I've ever seen, even on cloudy days. Even the foliage... read more of this plant looks nice. If you plant a group of them, they'll form a bush-like clump that looks amazing when in bloom. I absolutely recommend this plant, especially for those in the Monarch Butterfly's range. I found 22 Monarch caterpillars on my plants last Summer. Note: you may likely see aphids take over, but they don't cause true harm to the plant.

I grew these from seed several years ago. They are very easy to grow from seed. Here in zone 6 they are late to come about in spring, usually sometime in May. They take 2-3 years to become fully established and bloom profusely. But to me they have been worth the wait. I planted them in front of some heavenly blue morning glories that climb all the way up and over my roof each summer. The contrast of bright orange against the bright blue is stunning.
I was advised by a few experienced gardeners that this plant is, at some point, usually attacked and infested with aphids. You can leave them for the ladybugs to eat or wash them off with a soapy water mix. I tried to blast them off with just water and that did not work after several attempts.

I have started A tuberosa from seed in the past, but it had died out in my garden several years ago, so this year I decided to try again. Some seeds that I tossed onto an undrained flower tub and left under a snow bank, then allowed to drench in spring rain managed to germinate better than the ones I fussed over.

bjrailey: Howdy neighbor! I'm also from Concrete and have the much shorter yellow form of this flower (it also comes in a taller 3 ft. yellow form that is too tender for our area). Your post is dated March----way too early up here for these plants to poke their heads through the soil. It's at least late April in an early year, and last year it was into May. I just returned from the Nursery yesterday on the hunt for more of the short yellow variety and they said they won't have them ready until later June because of the slow start (they said that last year as well). They did have a lot of the orange and a few of the pink in 2 inch pots. I wanted the orange but was cautioned that they are prone to root rot in our winter rains and usually don't make it. So I got the pink which is "mor... read moree hardy and less prone to root rot". Give it a little more time. My established yellows popped above the soil late April. I cut mine to the ground every fall. I'm trying to get them to reseed from the spent flowers, but have had only minor luck. My soil is sandy loam and some of the info states these flowers like soggy wet conditions. That'll never happen in my garden. The new pink will be a test this year. Good luck and happy gardening!

Hi everybody! This is my first post. I need your help. At this time I have 2 of these plants and I just love them. I just need to know if I was supposed to cut down the plant for winter?

I just wanted to note that this should do just fine in dry clay.

Also, I recently had the opportunity to watch a Monarch Butterfly lay its eggs on an A. tuberosa. It wasn't flowering, so I don't think the flowers are what attract fertile females.

They do look pretty scraggly when the stripey caterpillars have their way with the plants, but people usually buy the plants for the caterpillars, not the narrow, simple leaves.

I am trying to support Monarchs ...
I have plot of asclepias that is now three years old, and I have yet to see a monarch butterfly come near it. There never seem to be many monarchs in our area. This year I had a huge amount of flower heads about to bloom, but it seems that something has eaten them. There are no bugs on the plants but the flower heads look like they have been chewed off. It happened last year too. Will monarchs still be attracted to milkweed if they have no flowers? What could be eating them? I'm thinking possibly racoons or groundhogs are eating the flower heads. If so I will move them and fence them off next year, but could it be birds eating them? If so I give up....

love this plant for the color of the flowers and the sturdiness of its structure. It blooms for a long time and needs no special care.

Aphids do seem to love it, but other than spraying them off with a hose, I dont do anything else, the aphids seldom do any major or permanent damage.

I planted 4 of these last year, without knowing much about the plant. Only 1 came up, it was under a rose bush, & didn't get enough sun. It remained small, but I did get some beautiful orange blooms on it.

Great butterfly plant, with additional autumn interest with the seed pods. Sometimes nursery bought plants haven't survived for me, but given an ideal location and care during their first year, they will thrive.

I found this plant growing wild in our local area, and the striking orange-yellow flowers impressed me so much I waited until the seed pods matured and gathered seeds. The first attempt to plant them failed, since I had not stratified them with the cold they needed to sprout. Later success has yielded several dozens of plants on my 1.25 acre lot. It is gorgeous, and attracts monarchs by the dozen when in full bloom. I allow the butterflies to lay their eggs and do what they will with the plants, since monarchs do seem to be in decline recently.

You can buy dormant Ladybugs, but will need to provide an environment that will hold them in your yard.

Several of the tiny wasps predate aphids as well, and they can be purchased also.

Every year I get aphids on my tomato plants, but with a week or two the Ladybugs and wasps decimate them, and they are not a problem for the remainder of the season.

I rescued some orange milkweed from the next yard when new owners were going to grass everything over. It thrived from the first day and 3 yrs later I divided it into 4 smaller clumps and transplanted them in 4 different places, two here in Dayton OH and two at my weekend home in St. Marys OH. They have thrived and bloomed all summer as before. I also have tall swamp milkweed that blooms pink and milkweed vine, which can be invasive, but I leave some for the Monarchs. This year some of the milkweed vine bloomed on a trellis with my sweet autumn clematis and they looked very nice together.

The aphids I get are very late in the season and I usually prune back the infested stems.

This is my second year with the plant and the first season for blooms. The flowers were very nice, but I (like many others) have aphids are ALL over the plants.... it does not seem to be harming the plant (other than it looks at little gross). I was happy to see a few caterpillars too. I'm guessing when there are more caterpillars, the plant may look a little ragged.

I don't want to spray anything since I do have butterflies and caterpillars, and bees all over these plants. I think instead I will just change the location for this plant. When visitors are waiting at the front door, the aphid infested plants are in full view. I think the caterpillars will increase and so I will just have raggedy, aphid infested plants.

Don't sweat the aphids, that's one of the great "uses" of this plant! It does attract aphids, but the aphids don't hurt the plant.

Since I've had some of these in select areas of my rose bed, I've haven't seen even a hint of aphids on my roses!

They not only attract butterflies, especially Monarchs, they are the larval food of the Monarch butterfly - so leave those beautiful caterpillars be!

If you don't want them to re-seed, simply cut off the seed pod before it opens. My experience has been that the seedlings are easy enough to pull if they aren't where you want them to be.

Try planting this plant with Tithonia rotundifolia (a perennial often grown as an annual that self sows) as A. tuberosa provides food for the larval stage of Monarchs, but Tithonia, or Mexican Sunflower, provides nectar for the adults, and Tithonia's spectacular orange-red flowers attract the Monarchs to your garden in the first place.

I recently saw the two plants growing together in a lovely garden in Gainesville, Florida, and the plants were covered with butterflies. Their orange/yellow flowers go well together, and the usually taller Tithonia, to about six feet, looked nice behind the shorter Butterfly weed. There are also shorter cultivars of Tithonia that would look good mixed with the Butterfly Weed.

As for the orange colored aphids, a good spray with the hose, or just wiping them off with some damp paper towels, will do a lot to diminish their numbers. They never seem to actually harm the plants, but I don't like to see them in my garden either, so I try to get rid of them, rather than get rid of the plants.

Butterfly Weed is very prone to yellow oleander aphids - it pretty much comes with the territory. Some farmers use milk weed to draw aphids away from their crops. You can't spray insecticide or you will defeat the purpose of the milkweed - to raise Monarchs (among others.)

This is the first year I've had a butterfly garden, and I've raised 4 generations of Monarchs off of it this summer! A couple of weeks after one batch of caterpillars was gone, another would appear - always in groups.
