I love this plant. Easy to grow (in the Bay Area). Lovely fragrant and great looking flowers. It does get big even when grown in a pot (big one though). I tried sprouting the seeds and got 80% germination without doing anything special. Gave the seedlings all away to spread the joy.

sanjosekate - I planted a couple of these in my backyard in Phoenix, AZ and they took off. They covered the entire length of the block walls surrounding my yard and creeped over the walls to decorate the adjoining neighbors' yards. LOVE THEM! Now I reside in Ohio, and wish I could grow them here. Unfortunately, I will have to purchase the seeds online and try to grow in a pot I suppose. I will keep you updated if I get them.

I don't think I could live without this plant, which grows at least 50' long and wide in San Jose, CA 95112! Sure, it can become messy and every few years I cut it to within a couple of feet, which means a truck load of kindling to do something with. But it produces many thousands of beautiful, unusual, and overwhelmingly fragrant flowers from July to September. Yes, they smell exactly like hyacinths. I never got one seed to sprout and grow, although I soaked them, nicked them, and babied them, so I splurged and paid $20 on sale for a 4" pot. But it is perennial here. I'm always trying to help friends in zones colder than 9 to propagate them, or find them online and pay more than you want to, plant in a container which you bring in for winter, and tell me how it goes.

Verdcourt created the name Vigna caracalla by transferring Phaseolus caracalla to the genus Vigna. They are by therefore definition identical plants. The problem is that Phaseolus speciosus (Syn. Vigna speciosa) or something very similar is often mislabeled as Phaseolus caracalla.

Bought 5 seeds from one source & 5 seeds from another. Didn't know what I was doing with the 1st set (didn't know I should nick the shell before soaking), and they didn't germinate. Dug them up & nicked the ones that hadn't rotted. Did the same with the 2nd set. Still no action. Dug them up again, and noticed some were trying to break free of the shell, but needed more help. The shell was leathery at this point, so I very gently tore it open more. Planted some 1/4" down & left some slightly exposed on the surface of the soil. The exposed ones immediately started to sprout. In fact, I noticed the germ/seed meat turned green which means it must need sun for producing energy, right? I'm no expert, but I suggest nicking the seed, let it soak for a couple of days, tear the coating open a bit... read more

Wonderful vine with a stunningly beautiful fragrance. This vine is planted in full to part sun (it is very warm here in Gisborne, NZ) and dies off in the winter and returns in spring. Easy to prune.

There is indeed much confusion between the two similar vines. To the people who have posted that this vine is invasive, I'd say you have the Phaseolus Caracalla. Even on Wikipedia, the incorrect photo has been paired with the name Vigna Caracalla. And one of the pictures on here (the fourth one down posted by justaysam) is NOT Vigna Caracalla.

Make sure you get the correct plant, and you will love it!

Although the photos show blossoms in violet, pink, cream, lavender, and white, mine seem to be almost completely lavender colored. The fragrance is so strong, I thought it was coming from roses I had planted nearby. A beautiful, easy-to-grow addition to my garden.

I picked up two of these under the assumption that they were Vigna Caracalla (Corkscrew Vine). One of the starts took off like a house on fire, covering an entire wall of my home in it's first season, and bloomed profusely (pairs of non-fragrant lilac blooms on long stems). The other kind of limped along, and never produced any flowers. I have since pulled that one out and replaced it with Vigna Caracalla which I picked up as seed from Summer Hill Seeds.

Even though the plant I received was not the plant I ordered, I am still quite pleased with the Phaseolus. It did get a case of sooty mold from the aphids last Summer, and I cut it back hard in the Winter, but it has come back with a vengeance this Spring.

It grows into the Cannas, roses and into the Brugmansia and snakes all over the deck, but never chokes the other plants, just grows and blooms ~ it's lovely and so easy to start.

I grew 2 from seeds last year. Both bloomed but only got 3 seedpods on one plant. Flowers smell very sweet, like candy to me. I let them go dormant for the winter. I left them in the pots (15" x 15") & poured about a cup or so of water on each one about once a month. The tops died back completely & I had my doubts that they were alive. This spring, I was happy to see them sprout & grow. One is blooming & the other has buds about to open.

It is planted in the ground, under an overhang, gets full morning sun, and is watered with the azaleas. Flowers bloom almost all year, but they are not fragrant. They are OK as cut flowers, or floating in a dish. It grew vigorously once I removed it from the container in which I had originally planted it. After 2 years in the ground there are no signs of invasiveness. No problems with pests of any kind. Los Altos, CA

I have had this one several years now and I dont think I am as impressed now as I was at first. It's a pretty bloom but comes with a price I don't really need. To many dropped seed and plants springing up every where. I guess our tropical climate is just to good for it. I will try and not grow anymore after this year.

I a going to take seeds and cuttings as I had a small one growing very well in a hanging basket, but it died over winter.

I bought this vine three years ago as a transplant. It is planted in a very drought prone part of my garden next to an arbor that it shares with Climbing Pinkie rose. The combination of the lavendar and white corkscrew shapes and the pinkie roses is exquisite. I thought the competing vines would be a problem, but they do quite well together. In winter the snail vine dies back and turns brown and brittle. It is very easy to pull the dead vines out from last year's snail vine and let it start all over again from the ground up. Mine blooms in mid to late summer. It's a very prolific climber

I started seeds bought from Park Seed and planted them in early May 2007, here in eastern Nebraska. The vines didn't start rapid growth until early July, and didn't flower until early August. However, once they started blooming they just went crazy - the vines totally covered my arbor and were incredibly loaded with flowers until as late as the end of October. Large dangling clusters of corkscrew flowers, purple streaks on a white background which faded to cream and then to yellow. Very fragrant, fragrance was noticeable from across the yard if the wind was right. I've already planted twice as many this year.

I agree that this plant is very agressive, at least in areas with long growing seasons, like here in South Georgia. I purchased it for a trellis 2 years ago, and within a few short weeks, it had covered the trellis, and wasted no time in covering a 15' x 40' planting bed. It froze to the ground that winter, so I thought I had escaped, but it came back in the spring - with a vengeance! My son & I dug it out this winter, after it died back - I hope we got it all - many of the stems had rooted where they touched the ground, so no telling!

I originally bought this plant from Spring Hill Nursery, believing that I was purchasing climbing shell vine (Vigna caracalla). What I they sent me, however, was snail vine, which proceeded, in less than a year, to take over not only my backyard, but also the backyards of three neighboors. It spreads as rapidly as kudzu and it's just as hard to kill--perhaps harder. I've not found any herbicides that work well on it. It might be affected by a freeze, but we haven't had one of those in New Orleans for several years now. Bottom line: I can't say enough bad things about this plant...

But I was mistaken, there were little gnat like insects in and around the blooms as well as something that looked like a very tiny earwig in the blooms.

I ordered two corkscrew flower vines from J&P and planted them in late April in Platte City, Missouri.

By early to mid-summer, they had taken over the trellis completely. I knew blooms weren't due to come until late summer/early fall, but I started to get impatient as summer came to a close. Finally around the first week of September, tiny buds appeared all over, and the first bloom opened fully a couple of weeks later.

It is fun showing friends and family the vine and its luscious blooms. They are amazed at it and want to know where I got it. I have given out lots of clippings. It is a beautiful vine that I am very pleased with. It will have a special place in my garden here in Missouri every year. I am bringing in clippings tonite because a frost is coming. Later I will dig up the tuber roots and store them till Spring.

well the one I had in the sunroom didn't do much so I put it on the trellis and it has grown more but still it is small,it only gets half a day of sun in that spot.

I received 2 precious seeds in a trade and experimented a little trying to germinate them. Soaking the seed without first nicking it didn't result in germination, but after nicking & soaking again the seed did sprout, so nicking seems to be important.

I nicked the seed coat, then soaked it for 12+ hours in warm, half-strength chamomile tea (started out warm, anyway, obviously it cooled to room temperature). The seed plumped up considerably with soaking. Then I put the seed into a scrap of paper towel moistened with the same tea and into a sealed baggie. In 2 to 3 days, I had germination! Temperature was a pretty constant 80 degrees, which may also be key.

I'll report again when/if I have an actual plant!

This is a must if you love beautiful flowers & wonderful fragrance. This is my third winter with this vine & while it does die back, it returns in the Spring ready to awe me all over again. I had to pick the seedpods green this year due to early freeze, and let them dry indoors. I was sure they were not viable, but of the 8 seeds I planted on Jan 1st, 2005, 6 are already sprouted. The seeds need to be nicked and soaked overnight in the hottest tap water y... read more

Saw a picture in a catalog and had to have it. Couldn't find any seed, so I had to order the plant this spring. It arrived with 5 yellow leaves and was bone dry. It lived & does quite well in a container (zone 5). It has the lavender flowers, what I saw was the pink & cream, but I'm still happy. It's so unusual! Hopefully it will over-winter well & need a much bigger pot next spring! There were a few ants, but no seeds.

This plant does so well in the Las vegas sun. Never had an aphid problem. Have a praying mantis living in it.

Snail vine grows very well in zone 10. It does not lose its leaves in the winter here in southern California. Also the young flowers are quite tasty and add beauty to a salad!

This plants LOVES humidity and warmth. The only time it put on sigificant growth and the leaves actually opened (instead of laying flat and closed) was when it was in the 90's and VERY humid outside.

If the right conditions are provided, it'll grow well.

I love this plant, so unusual and the leaves are stunning. It requires ants to pollinate the flowers for seed, so I allow ants to run freely on it, yet I have never found seed one. I keep it in a pot and bring it in to the winter greenhouse so it stays green all year. Lots of cuttings are easily made from the one plant. I have read that if you trim it back Nov to Dec you will get blooms in Jan to Mar but I have not tried it yet.

I purchased 2 of these from Logee's Greenhouse at a very reasonable price. They arrived in excellent condition and I put them in my kitchen window which is a southern exposure. After losing one and almost the other due to an aphid infestation and one very naughty kitty, I now have it in my bathroom window which also faces south. My bathroom does not have an exhaust fan and since it is now growing like crazy I assume it likes the warmth and humidity. I'll let you know when it blooms!

This is a charming non-fragrant plant. Interesting blooms and readily availabe in our area at most nurseries. Mine freezes to the ground and rarely comes back.

I planted this plant as seeds in a container this year for the first time. The plant was quite vigorous. When it was planted it was expected to be an unusual bean. It was very unusual.
The seeds put out long tubers that infiltrated the container watering grids. To take them in for the winter (Pennsylvania gets cold) I had to cut the grids to get them out. I expect that in the ground they would be quite invasive and impossible to eradicate. Beautiful flowers but no seeds this year. Maybe next year. I will plant them in their own containers next year.

I found this plant called Snail Vine at Walmart a few years ago. I'm drawn to unusual plants so I got it not knowing what to expect. The first couple years it didnt do much but the third year it took off and grew! I love it! I dont seem to have the aphid problems listed but I see ants on it but since they dont eat the plant I see no harm. Others have commented on how wonderul this plant is and want one too. I'll share mine. Here in the high desert of Southern California this plant starts blooming in July and goes til it gets nearly 30 degrees which is Mid November. It does die back each winter but comes right back in April- May. It takes no maintenance other than cutting it back a bit.

I do like this plant. I use it on my fence for privacy, but in the month of September it turns all yellow and all the leaves fall off. Someone else in my neighbor has these also but they do not yellow and fall away. I irrigate them, so I'm not sure what the problem is.

It is a beautiful, easy growing, fragrant and attractive vine. It attracts lots of spiders which is a real positive for natural bug control. In Australia I have only seen the cream variety with the purple centres which are also very beautiful. It is deciduous in colder climates which is very beneficial for blocking sun in summer and letting the sun filter through in winter. Stunning green foliage.

Have to agree with cmoon... very invasive vine. And a great attractor of aphids. To keep it aphid free would require weekly spraying... seems to attract ants, too, which love to run along it's highways about the yard (at least morning glory, the other nasty invasive vine in the yard, doesnt' attrract the ants). Hard to get rid of this plant, but it is at least somewhat sensitive to Roundup. Be very careful where you put this thing.

There seems to be some confusion among botanists and commercial sources on what to call Phaseolus caracalla and Vigna caracalla ("Snail Vine" or "Corkscrew Vine"? Which is which???) and whether or not they're synonyms.

Comparing the images should at least estabish that they are NOT the same vine. Whether P. caracalla is Snail Vine or Corkscrew Vine...who can say for sure? ;o)

About 4 months ago, we put in our back yard and needed a plant that would cover our back fence very fast! So we went to a local garden center and asked about this vine with very pretty flowers; we were told it was a snail vine. They told us it would do well so we bought 4 plants and spaced them about 4 ft apart. They have now been in for 4 months and you cannot see our fence at all - this vine is a fast grower. We are very happy with the way it has spread and covered our fence.

Tip" I dug a trench then planted the vine down in it so I could flood them; seems to work well for this vine! Water about 2 times a week (I also used a complete lawn food.)

I went to Monticello and saw the plant and had to have it, it is so interesting. I bought it in the early fall I left it in the pot and cut it back to 1' and put it a dark area with no water (my crawl space under the house). In the spring I brought it out and it has grown well (I live in southeastern VA). The one odd thing is one plant is blooming (I bought 2) and the other has not bloomed, but is growing what looks like berries, not seed/bean pods.

I planted this in May in Northern Virginia, and while the vine has grown quite well, it has yet to produce a single flower, and it is already August 1st. Ocassionally, a couple of leaves will turn very yellow and die. Also, the plant seems to turn slightly yellow at times. We have had plenty of rain here, and when we get a long dry spell I do water it. I have also fertizlied ocassionally.

Purchased this from Monticello Thomas Jefferson Foundation. It arrived in excellent condition and by Federal Express all for $10.00

The bare root of this vine sure is funky looking. They said in the instructions that "the root you have received was grown from seed during last year's growing season. After growth died down in the fall, the tuber was removed from its pot and stored over winter in boxes of moistened sphagnum moss in an unheated room. Growth will begin anew as the season warms in late spring."

My Corkscrew Flower didn't put out a great deal of foliage, and was a much slower grower than its counterpart(my snail vine), but the blooms have made up for it! Their curly(cream with violet accents) bloom clusters are very showy and smell like Arabian Jasmine-(at least to me). It is a strong scent, and can be smelled in the air without even getting up close to the bloom! If you get REALLY close, you can also see a blue with yellow marking inside the flower. Absolutely fascinating. Everyone that has seen mine says the same thing-"wow, what is that?"...

This vine is great for a fast cover. It is a very vigorous grower, with dense and profuse foliage, and will get monster size in no time.
The blooms are beautiful purple swirly blooms. There are usually two to four blooms produced on horizontal-(to drooping) stems. It blooms constantly and consistently, from Spring to frost.
It puts a great deal of foliage. It also does not have the strong scent that its cousin the corkscrew does, but still worth growing.
Snail vine is extrememly easy to propagate. I have proagated these in wet sand with as little as one leaf petiole.
The pollinator for this flower is not the ant, though it was once believed to is the large carpenter bee/bumble bee.

The fragrance is out of this world, and the interesting flowers are a favorite of any visitor to our gardener. This plant will be in our gardens every year from now on.

A note: It is a tropical perennial, and not hardy in most of the United States. I grow the plant as an annual, and right before the frost, I take a few cuttings to overwinter until the next spring.
