The air potato is indeed a major league nuisance species and should never be introduced to new locations in south and central Florida or in the southern portions of other Gulf states where it can over-winter and continue its invasive behavior. Florida, alas, is so heavily contaminated with exotic invasive plant species that, in my professional opinion, it is futile to hope for any kind of recovery to natural conditions in most of the southern 3/4 of that state. A fairly recent menace is the dreaded Cogon grass, which is useless as a pasture grass and quickly occupies large areas of lands once suitable for pasture. It is becoming the dominant land cover over much of the right of way of Interstate Highway 10 in Alabama and Mississippi. In the southern half of Florida, two trees, Melaleuca quinquinervia and Schinus terebinthfolius, have invaded numerous natural areas, including the Everglades and Big Cypress Swamp. These are very expensive and difficult to eradicate. The irresponsible and ignorant actions of humans is responsible for this environmental tragedy!

Naturalized from Texas to Georgia. Alabama and Florida have listed it as a noxious weed. In Palm Beach County, FL, where I've gardened, this is one of 9 legally prohibited species. This is also a pest plant in Hawaii.

"Noxious weed" is a legal term for a plant that causes problems in agriculture or ranching, and for which the state has the legal right to come onto your land to eradicate the plant and charge you for it. It also involves stiff fines for transporting, selling, buying, or planting the species.

Native to Africa, southern Asia, and Australia.

Air potato started growing in the area between my house and the neighbor's place about five years ago (don't know how it got there), and ...Read Morewas scrambling up the crepe myrtles. The extra leaves added to the wind resistance of the myrtles (not good during hurricanes and high winds!). I decided to eradicate it. Well, it's taken three years of diligently pulling up the sprouts, but I think I've finally done it. Not one came up this spring. So it can be done, but you've got to be patient and keep at it. Plus, it was an area of only maybe 300-400 square feet total. As many folks have said, if you live in the humid subtropical South, do not plant this.

Bulbifera has staggered leaves while the alata has paired leaves. I cultivate the alata here in Florida and have been for years. I use them for everything from flour for bread to just a normal substitute for potatoes. IF you put work into it they won't spread. I recommend digging an unfenced plot in the middle of a field with nothing for it to climb on. This way your potatoes stay manageable and the tubers don't get mangled and nasty looking. Simply kill anything that escapes the hole. Just to be on the safe side once I harvest every year I burn everything but the tuber which I replant for next year. If your careful the alata can be a wonderful and delicious plant.

YIKES! That vine that ate the Kudzu! These things are crazy! I have watched over the years a field that is the size of a few acres becomi...Read Moreng blanketed by this weed over, and over, and over. But wait, I must tell you the story of this field first.
In 2004, the storms came, and went. These stroms blew all the invasive's seeds right to this very field. (This field was not infested before the storms.) I now call it "the battleground" beacuse that is just what it is, all sorts of invasives competing for sunlight, soil, and space. This field has been mowed around so they are all limited to this space. The field at least consists of these invasives:
Air Potato, Kudzu, Skunk Vine, Old world climing fern (The old world climing fern just showed up in the middle of nowhere, and is gaining speed) Cogon Grass, Non- Native Lantana, and a few others. Well guess what?
The Air Potato is killing the Kudzu by mass numbers!
I wish I could tell everything about the field here, it is intresting to see what invasives are the worst! I might post something in my daves garden blog that is under development about it one day! Overall message: This one might be the worst of ALL invasives here in Florida!

Happy Gardening!

This plant is evil objectified.

The home we are currently renting is located next to a house which was owned by an elderly...Read More lady who died, and whose lawn service was only going through the motions (doing the bare minimum needed to keep the place presentable). I don't know if it was planted deliberately or was an accidental growth, but this plant has crossed the fenceline and I have been kept busy digging up newly sprouted tubers, and cutting back the horrible, snarled vines. I actually went into her back yard on Monday and pulled out three lawn-and-leaf bags full of air potato vines, trying to pull out the tubers as well. I found three dead shrubs/small trees which were simply serving as trellises for this noxious weed. While cleaning out the mess from the air potato, I also came across a Chinese tallow plant (another exotic invasive) which was removed along with the air potato. I have been collecting the potatoes whenever I find them, because the only to ensure that they will not sprout is to freeze them. Otherwise they will sprout at whatever landfill they occupy.

I'll add a positive review of this plant. I pulled up a sprig growing in Rockport, TX three years ago and planted it to twine up an old o...Read Moreak tree. The leaves are indeed beautiful and it gave me a handful of seeds. It died off after a cold snap in winter. I planted the seeds the following spring and they all died during last summer's record-breaking heat and drought.
I agree under good conditions in places like Florida, they can be a nuisance, but here in S. Texas the weather keeps them from becoming invasive.

I live in Zephyrhills, FL. and i brought home a couple of "Kudzu" potato's a few years ago. All this has done is propagate over and over ...Read Morefrom every potato that develops on the vine. The reason it kills tree's and shrubs is because it grows so well in the humidity and shade, it also sucks the water out of the ground taking it away from other plants you want to keep and filters out the essential and beneficial sunlight that normal plants crave. Once you have it, it's yours forever, and keeping up with the potato's is a losing battle! Even the tiniest node will produce a plant that grows 60 to 80 feet into the sky, up tree trunks or anything for it to climb on, and as stated by others, it WILL take over your other plants and KILL them! I DO NOT recommend planting this ANYWHERE because you will NEVER do enough to get rid of it !
The other really invasive plants, is the "Brazilian Pepper Bush" which has dark beautiful dark green leaves, and the bright red seeds it produces will take over your yard where-ever the seeds fall in the fall. I hope you will take a second look and think twice before you introduce this plant to your yard, because it's just not worth the time and trouble that it takes to remove it!

GET RESPONSIBLE IN YOUR PLANTINGS. FAMILIARIZE YOURSELF WITH THE INASIVE EXOTIC SPECIES AND DO EVERYTHING YOU CAN TO ERADICATE THEM. And for god's sake, don't sell them and don't plant them.

It took about 2 weeks or more for them to germinate but I got almost 100% germination. They grew fairly slowly at first and about the time they were taking off, the hot weather hit and they slowed down a lot.

I planted them all on a chain link fence except for one in a small pot with a stick in the middle. I think only two have survived on the fence and the one in the pot survived well and did the best. Just two days ago I noticed it made around 10 potatoes. I promptly planted them in the ground. I think this plant doesn't like extreme heat and will do better now that cooler fall temps are here.

NASTY PLANT!

This vine was growing in a park across the street from my house and killed pretty much every tree in there by...Read More choking them to death. It was pretty sad to see all of those trees gone. Now of course, it is starting to sprout up around the yard. I kicked it old school and yanked some up yesterday. But there were a few that wouldn't budge!

I read that Round-up will work too. Gonna try that and see what happens! Hopefully, by doing my little part I will keep then from spreading some more and killing off any more trees. There are some pretty old Banyan trees in my neighborhood... it would be sad to see them killed off too.

If you are in Florida, please do the rest of the state a favor and DO NOT grow this plant. As pretty as you think it might be, it's choking out our forests. It can wipe out several acres in a matter of months. It is said it can grow 8 inches a day!! There are plenty of other vines that are even prettier and won't harm the environment.

As you might think a yam relative with hot and wet/humid needs isnt going to become invasive in California. Keeping it going year to year isn't easy.

I acquired a lo...Read Morevely 3 acre CLEAR lot with naturally moist, fertile soil. I wanted to grow something and I thought the vines I had seen growing wild in the ditches with the heart-shaped leaves would look nice and lend an air of "quick" fix for my naked land.

WHAT A HUGE MISTAKE!!! I spent the next 30 years battling this plant as I watched it quickly take over every square inch of land.... the house, trees, EVERYTHING!!! Hundreds of dollars were spent on herbicides in my attempt to rid my property of this PEST. I spent thousands of hours with a machete in hand cutting, ripping, pulling,....... ANYTHING to try and rid my land of this vine.

Every single potato, no matter how tiny (they could be the size of a pea) grew and flourished. The underground tubers grew to weigh 20 lbs. or more. The squirrels carried the fruits all over the property and onto the neighbor's land.

The large, strong vines grew from one treetop to the next and eventually covered the whole place in a blanket of vines. During the hurricanes of '04 all it took was one or two trees to start falling and the domino effect went into play with the common "link" being their binding together with this vine. We lost almost every single tree in our yard.

Anyone who is even considering growing this vine is welcome to come view some areas of Central Florida and see what can happen in a very short time when this thing gets busy. You can even come see what it has done to my once beautiful, clean, CLEAR 3 acres of land, just be sure to bring plenty of Round-Up, some machetes and pack a huge lunch and plan on staying awhile as you can help me try to eradicate this horrid pest from my yard.

This gets top vote as the absolute most invasive, noxious exotic EVER!! Anyone who gets this thing loose in their yard, I feel for you and you are going to be facing a virtual losing battle as you try to control, contain and eradicate it from your land. Good luck cause you are going to need it!!!

Comments [advocating planting it] show nothing short of a full disregard of natural environments and law, considering this plant is listed on every invasive list there is for Florida and is illegal to possess. But congratulations to the author! That post has now been memorialized in a Florida Exotic Pest Plant Council paper about Air Potato.

According to that same paper, "Air potato causes ecological damage by climbing other vegetation and forming dense canopies that shade out, and may cause the collapse, of native plants (Gordon et. al., 1999; Schmitz et al., 1997; Schultz, 1993). Air potato is listed by the Florida Exotic Pest Plant Council as a Category I invasive plant--species which are altering native plant communities by displacing native species, changing community structures or ecological functions, or hybridizing with natives."

Air potato was introduced into Florida in 1905, and in just those hundred years has spread into nearly all parts of Florida, from the Panhandle to the Keys, taking over native hammocks along the way. It is a state listed noxious weed, and is illegal to introduce, multiply, possess, move, or be released except with permit from the Florida Department of Agriculture and Consumer Services.

Look at the symmetry of the leaves and the veining--they are stunning.
