Before a friend gave me some Tropical Milkweed seeds 3 years ago, I'd seen maybe half a dozen Monarchs in the 7 years prior to that.

Everyone interested in growing the Asclepius curassavica, be aware... Please research Ophryocystis elektroscirrha (OE) and understand it's effects on the Monarch butterfly population. As responsible gardeners and stewards of our wildlife, it is important to only plant varieties of milkweed native to our areas.

This plant is about the most beautiful Milkweed there is. This is the only good I can say about it.

I was tempted to plant it for that reason and that I heard it is easy to grow. I actually tried ordering it from the local nursery even with some qualms I had, but not allow them to develop seed and yank them out at the end of the season. My native Milkweeds have been slow to establish and I wanted this for a food source until that happened.

I am so grateful the owner ordered the native A. tuberosa instead. And they did much better than I expected. If they spread, they belong here and will not upset the delicate balance in our area.

In the warmer climates, Asclepias curassavica has become a naturalized weed and unlike in colder regions, t... read more

This is NOT a plant that should be planted anywhere in the US where migratory monarch butterflies can be found. It can interfere with the monarch migration and help spread a protozoan parasite that adversely affects monarchs. Research was published in January 2015 detailing how Asclepias curassavica adversely affects monarchs in the southern US. I don't think I'm allowed to post URLs but you can Google "Plan to save monarch butterflies backfires" to find an article that has a link to the research.

My experience with it in central Ohio is it is not an annual. It has been coming back up in my yard for 5 years even though I don't let it go to seed.

Such a beautiful and productive plant that flowers nearly all year in Phoenix. My plants are scattered throughout the yard from full shade to morning-only sun as the Phoenix summer heat tends to stress this milkweed. The seed pods pop in the winter spreading tiny white feathery seeds around. Hummingbirds go crazy over the brilliant red/yellow flowers and the queen/monarch caterpillars are such a delight during migration. A must have for every yard in the south.

Originally I had bought this plant from a greenhouse to attract Monarch Butterflies. I read it will not survive the cold. My plants spread hundreds of seeds all over. Not only next year did a few plants come back that were planted in sheltered areas like under shrubs, I had loads of seeds survive the snow and frost of winter and sprout late spring which amazed me as they were growing wild without my help. I've even had seeds emerge almost 6 years later when they were dormant under old soil that was recently turned and the seeds sprouted! Where I live can be 7a or 7b so plant file should be updated! I hope more people let there's set seed and plant them in the ground.

I grow this one from seed every year, as it is not hardy in my garden in zone 7b. I have had no problems with it seeding all over my garden (I wish!). I collect the seeds every year. They wintersow quite well, and I put the seedlings into the garden to grow in time for the monarchs to arrive in august. it's their favorite host plant. I grow tuberosa and incarnata as well and they always pick curassavica first.

This plant easily thrives in a garden where it takes immense effort to grow most others. (This spot in full sun dries out terribly and is often used as a latrine by neighbor cats.) I also have a successful plant in a rather shady back garden. I use "homemade horticultural oil" (1 Tbs cooking oil & 1 Tbs non-degreasing dish shop in a gallon of water) to eliminate those yellow aphids when they show up. And I seem to have more butterflies since I acquired these plants. I no longer worry about this plant when it seems to have always comes back.

I planted mine several years ago. It is beautiful when it blooms and monarch catapillars do love it. But mine does not seem to grow very large nor spread. Each year it comes back but never bigger than the year before. Not sure if it is the location or the soil.

I live in northwestern Vermont (Zone 5a). I planted this beautiful plant last spring, and to my surprise it came back this year, and has buds right now. It died down to the roots, but started growing this spring again. Very pleased to see it come back this year - I had a hummingbird that seemed to enjoy it last year. The orange was a nice contrast to the purples, pinks and yellows in my garden.

I purchased some 'butterfly weed' on sale with no Latin name. It bloomed wonderfully all last fall and was quite the stunner for many weeks. It did not come back but I noticed several seedlings near where the mother plants were planted. I believe it to be this Mexican butterfly weed. And Wow! Lots of baby seedlings of this colorful milkweed. It does get aphid infestation but that has not damaged the plants. A real keeper and longer blooming than A. tuberosa.

I originally ordered seeds for this plant from a Monarch butterfly website back in '91 when I was living in Monterey, CA. The plants did fairly well, but didn't like the cool weather and shady conditions it had. It bloomed, but didn't set seed the first couple years. Fortunately, my original seed remained viable during those years so I was able to restart some each spring. Finally, I got one to develop seed so I was resupplied.

I then moved here to Colorado Springs with a warm sunny backyard. The plants exploded into growth, bloomed, and produced copious amounts of seed. I'm now set for life, I think. The first summer the seed pods opened and seeded themselves in several of my other potted plants which were then over-wintered indoors. The following spring I had even more pla... read more

If grown from seed in my Z5 - I must start it indoors 8 weeks before last frost. If I want to be able to collect seeds for growing again the next season, even earlier. It is a tender perennial here and will not reseed itself, nor come back from it's roots. It is an easy way to have a lot of Milkweed for the hungry Monarch caterpillars. Which are another reason for the need to start it early here. They arrive about mid July - so you need to have your plants practically ready to set seed. Otherwise they will eat it all up before it has the chance. They eat it down to stems - but tend to leaves some seed heads, if they are there. They will eat the blossoms too.

Well, the supposed zone 5 plants did not come back the next spring but had left hundreds of seeds behind that sprouted liberally everywhere. I had so many I potted them up and gave them away, and I still had about 200 plants (most were red-and-yellow) that summer, and even more Monarchs.

Here in Houston zone 9a, I can just cut the canes which get almost 5 feet tall, and stick them in the ground or in a pot and they take root and grow. About 1 week ago, my biggest plant looked like a caterpillar bush... not a leaf left on it and covered with about 40 big fat caterpillars. The next day I found them crawling everywhere looking for a place to "hang". I and my neighbors enjoy them so much. I have not seen any "volunteers" from previous year's seed. It's probably too windy here. My seeds may be in Oklahoma by now! I was disappointed to find the huge strange-looking aphids but I used the soap and they were gone quickly enough. Ive planted lantana, pentas and Mexican flame vine for the adult Monarchs to use as nectar plants.

I've considered a milkweed for my butterfly garden but have been concerned about it spreading. We have a horse farm and I don't want it to get out into my pastures. I posted on the Herb forum about it and a gal in Tx said she said not all varieties are invasive. Which ones aren't? Also, I've got a protected spot (corner) where I have my herb garden by the house and porch. Would it grow in a pot there (lots of sun) if I put it in a pot and deadheaded it? I could keep a close eye on it there.
Thanks for any advice

MARCH 2014: Six yrs after orig posting, butterflies hv recognized my garden as butterfly friendly and consume this plant readily. There has been moderate spread but since this plant is so vital to butterflies and my garden has. the space, I have no problems with it.

It spreads out very quickly. I bought it for our Butterfly Garden. It is interesting to see it has popped up in other areas in my yard from the seeds blowing around.

I keep it cut back between 30" - 38" Tall & try to keep it under 48" Wide. Due to the seed pods popping open before I can collect the seeds, It can overtake your garden if you don't watch it.

Humminbirds have been seen hanging around this plant in addition to butterflies & bees.

This plant grows very well in the New Orleans area. Many nectar/pollen insects and hummingbirds are attracted to it. It self-seeds easily. It can also be transplanted if you remove a large and deep amount of soil with the roots.
The major problem is with severe infestations of yellow aphids. Infestations have been so bad that some plants have been killed. According to info on other pages, the normal aphid predators are poisoned by them because they absorb the toxic sap from the milkweed. I also have problems with milkweed assassin bugs infesting the plants and attacking insects that are attracted to the plants.

I recieved mine in a plant trade from one of the members on DG. It did very well for me, starting from young plants. I hardly watered it and it had very showy blooms. I noticed in early August this year the Monarch butterfly larvae were feasting on it. Great, I love to promote butterfly production. The seed pods were a long pointy paper looking seed pod which contained the "fly away"seeds. Each seed was tethered to a light white fiber that helped it to be drifted by the wind. I collected all the seeds I could and plan to plant the seeds in my new raised garden bed for next year. Considereing the extream drought of this year, I would definitely recommend this plant for conserving water needs!!

I got a few seed pods from my neighbor's plant (who has no idea where it came from). Every single seed sprouted and all seedlings are doing excellent. They do very well in our area.

One thing though, pinch out the centers to have the plant branch out more. It doesn't take much pinching to get it to branch. I'm doing this before they are large enough to bloom so that they will be fuller and provide more blooms.

In my native Maryland, zone 7b, I grow this as an annual. It's helpful to start the seeds inside in early spring or even sooner or else you won't get blooms until late winter or early fall.

Since these are growing as annuals I can't say my plants ever have the chance to get that tall and so the butterflies usually pass over the curassavica for one of the taller perennial milkweeds.

I've noticed curassavica's leaves are a lot more tender than my perennial, hardy milkweeds and so the monarchs prefer the foliage as larval food.... and so do the aphids which cover the plants almost entirely.

The other milkweed bugs, such as the beetles, usually pass this milkweed over because it never becomes thick enough for them to bore into or provide substantial... read more

San Antonio, Tx

This is an excellent tall xeriscape plant that takes at least a year to become established with more branching enabling more blooms. The seeds float off and readily create new plants that can be transplanted or potted and given to friends and neighbors. This must be accomplished when the plants are small. It has a long tap root, so it is somewhat tricky to transplant once established. If heavy invasions of aphids and other insects are not removed, the leaves become an unattractive, mottled yellow/brownish color. Butterflies and bees love this plant which blooms constantly from June to early September in my zone. Being a perennial, it dies back after the first hard freeze and reappears in early spring.

I like the colorful flowers which attract butterflies. This plant blooms through the winter when almost everything else is dormant. It is a great larval host plant for the Monarch and Queen caterpillars. Spider mites and Oleander aphids (the yellow-orange ones with black legs) can be somewhat unsightly, though they don't seem to harm the plant. Caterpillars have eaten the growing buds completely away and the plant will sprout back from lower on the stems or at the base of the plant. It will do the same after a hard freeze. It also grows readily from seed.

Scarlet milkweed is an erect, evergreen perennial shrub, often grown as an annual in colder climes. It gets about 3-4' tall and usually has a few pairs of symmetrical branches.

Scarlet milkweed is easy to grow, thriving in all types of soils in Zones 8B - 11. It remains evergreen in zones 9B-11, but if it does freeze to the ground, it usually comes back in spring. Scarlet milkweed can be started from cuttings, and it grows quickly from seed.
