I've had moonflower vines climb my trees and attain a height of 50 feet. A lot of people who appreciate this flower may not grow them for that reason. Some may not have any structure for the vines to climb.

I have good news for those people. It may be common knowledge to many gardeners, but new to me is the fact that the vine will grow quite well, and bloom, in a container. It just occurred to me that they should do well on a trellis of 6 feet or so. I say that because once the vine has reached the desired height, it can be pruned. Cutting back the new, long runners seems to force the vine to produce even more blooms.


If you have been hesitant to grow the moonflower vine because of the heights it can reach, do know it can be kept in a container and it's ultimate height can be whatever you choose. Imagine having a pot of these on your patio, covered in blooms, and filling the air with it's heady fragrance.

The moonflower vine (which will be considered Ipomoea alba throughout this post) is a beautiful plant; a bit mysterious, too. I have read numerous internet accounts of this vine. The most consistent fact in these accounts is the inconsistency in their 'facts'. Even the origin of the moonflower vine is in question. Though it has been introduced to many temperate regions of the world, such as India, where it is highly prized; we can assume by the nature of the plant, its origin is tropical, most likely, the New World tropics.

Note: Earlier, the moonflower vine was classified as Calonyction aculeatum, and is still sold by some seedsmen under this name. However, according to Wikipedia, it has been "properly reassigned" to the genus Ipomoea Quamoclit. Oddly enough, Wikipedia also lists the cardinal vine, aka, the cypress vine, as Ipomoea quamoclit. Until the taxonomists come to terms with the name of the moonflower vine, I will refer to it as, the widely accepted and probably more correct, Ipomoea alba.


Having read so many articles on this vine, I can only assume most are simply copied versions of articles found elsewhere on the net. Incorrect information is re written as fact and passed along, yet again. For example, most of these numerous articles cite the moonflower vine as being toxic or poisonous.

For the sake of brevity, I will not list the four web pages I found citing the moonflower vine as edible, and extractions from same used internally to treat certain disorders. I will, in the interest of those who would like to grow this vine, but hesitate due to fear of safety in doing so, present two facts attesting to the innocuous nature of this plant.

Some of you will remember my little friend, Robbie, the orphaned rabbit. In a post I made earlier, I said Robbie was an 'anyvore', because he would eat anything. Indeed, I mentioned he had been eating the leaves of my moonflower vine. At least two months later, he was still alive and appeared quite healthy.

When the vines began to bloom, I remembered witnessing Robbie eating the leaves. Being confident there was no harm, I selected the largest bloom. I ate the whole bloom. I suffered absolutely no ill effects. Two months later, I am alive and quite well for my age.

What with the four accounts from reputable sources, citing the edibility of this vine, even the young seed, and with my own personal ingestion of it's flower, and with Robbie relishing it's leaves, I think no matter how many articles you read citing it's toxicity, you can grow this beautiful vine without fear or worry. Just be sure you are growing moonflower vine, Ipomoea alba, and not some of the other plants commonly termed 'moonflower', which indeed, are poisonous.

As to the misinformation contained in most articles on this plant, the words of an old friend come to mind: 'Doug, don't you know a piece of paper will lay there and let you write anything on it?'.

Members have written in, complaining that their moonflower vines were taken by frost just before they were about to bloom. I told them the vine requires a long growing season.


I advised them to start the seed indoors, beginning as early as late February. I have more information to share.

Last Fall, I collected seed from the dried seed pods on the vine pictured here. I brought the seed inside and put them in a saucer to dry for three days.

Can someone tell me where I can locate seeds or the plant in Northeast Dallas area?

Last year I grew moonflowers, and late in the fall I harvested a couple of dozen seeds from the purple-ish pods. I kept them in a cool dry place all winter.


After reading online, I took a dozen or so and soaked them in water overnight, then planted them about 1/2 inch deep in seed starting soil mix in jiffy pots. It's been about 3 weeks and none of them have germinated.

I put the rest in the fridge so they'd have a brief cold season. I then separated them into three groups of four: 1) soaked in water, put in soil, then placed on a seed-starting heat pad; 2) soaked in water in the fridge for two days, then put in soil and on the heating mat, and 3) placed the seeds in soil-filled jiffy pots, then placed in the fridge for another 24 hours. These were not put on the heating pad.

It's now been a week, and I have yet to see any sign of germination. It seems I tried everything (except for nicking the seeds) and had no luck. Any idea what I did wrong? Is it possible to dig up the seeds, nick them, and put them back in the pots? Or is it possible that somehow these seeds were not viable?

Moonflowers are extremely toxic to all animals. Do not plant them. I would suggest this website for some pretty and unusual flower seeds.
Contact them with any questions regarding the flowers' toxicity and benefits to butterflies, hummingbirds and other animals. Also, whether or not the flowers would work well in your geographic location. I've found them to be a great resource.

I received dried moonflower seeds from a plant in Dallas. I put some in pots with potting soil and planted some directly in the ground without nicking and soaking. It's been about 2 weeks now and none have sprouted. I have done an online search and everyone says to nick the seeds. These seeds are so tiny it's about impossible to nick them. I now have a few that have been soaking for about three days and they don't look any different from the day I starting soaking them. Are the seeds in the packets that you buy any bigger? I'm in zone 7, west Texas. What am I doing wrong?

I did not nick mine but I did soak them. It took a long time for them to come up but once they did they are growing fast.

Moonflower seeds pods are easy to identify. As the flowers fade you will see large purplish-colored pods. Some gardeners like the looks of them and leave them attached to the vines, while other cut them off. To save moonflower seeds, collect the pods once they turn brown and start to crack open. If you're worried about frost before the pods dry out completely, remove them and finish drying them inside. Inside the pods will be hard, cream-colored seeds. These seeds sometimes take a while to dry, so you may want to store them over winter in paper bags to ensure they get some air circulation. In the spring, nick the seeds slightly and soak them overnight in warm water. This will help speed up the germination process before you plant them. Start the seeds indoors for transplanting or sow them directly into the ground once danger of frost is well past.

While they are green and about to pop open, you will see many seeds. Drop them where you want them ,to grow, or just let them fall to the ground, and they will come up next Spring.

After the flowers fall off, there will be a seed ball form. They will get to approximately the size of a golf ball and have little spine like on them. Clip the stem and put them in a dry place to dry out. After the pods are dried, you can remove the seeds and put them in a container to plant the next season. I hope this helps.

I always let my plants reseed themselves which may be a mistake because the plants can
get real invasive thru the season. Next year I will collect some of the pods off the ground.
I did hear this summer that when cutting the plants back wear gloves because the juices plant are that ooze out of thehallucinagetic, not sure to what but better safe than sorry.

Moon Flower seeds - Shouldn't be a problem collecting seeds as every flower makes a seed pod. So they are there all season. Plus remember that these seeds [toxin] famous for its mind altering properties. I have grown them, they smell wonderful. I always wash my hands when I have handled the plant.

I planted moonflower seeds, how long do they take for germination?

I think they take a while. I live in Central Florida. If I remember correctly, it took a while, maybe even 10 days or so, but I planted them directly in the soil. Then the plant started to grow and vine. By mid-summer it bloomed. I believe I bought the seed from Martha Stewart at Kmart. Good Luck!

Hey, did you soak them? I soaked mine overnight and I think they took about what the package said, maybe a bit longer. I kept them pretty well watered also.

Surprisingly I have had great luck sprouting moonflower seeds which are six years old between pieces of moist paper towel. Then I will transfer to peat pots. My question is this, when one sprouts, it sends out a white worm like looking thing. It grows. Will this be the future root? If so, I should place in plant with that part going down, right? Thanks!

I planted these last year and they came back. I love them! I wish I would have planted them in my angel garden; I may do that in the fall.

They're show off flowers for sure :) with huge blooms. It is a shame each blooms for one evening, yet there are always more blooms. At the moment I have 14 buds. I can't wait for every evening to see new blooms.

They hold up even with all the heat we're having this summer. I consider them a keeper in my gardens and when the full moon shines on them they are breath taking!

I took these just before dark last night. I hope you'll enjoy seeing my moon flowers and maybe even plant one for your garden. :)
