My nomination for Invasive Plant of the Year: Bittersweet.
Dad thought it would be neat to plant this thing at the
shady end of the old grape arbor where the grapes have
pretty much died out. Dad is gone now, but the bittersweet
had become quite robust, taking over most of the grape
arbor and had migrated over to a power pole and was two
thirds of the way up. The latter looked like an especially
bad idea. So I decided that it has to go, and after a half
a day of digging, pulling, and cutting, I'm confident that
I have failed to eliminate it. Who would have suspected
that even a quarter inch vine shoot connects to a one inch
root below the ground's surface? Yes, it has lush green
foliage and pretty red-orange berries and grows fast. I
suspect it may even be sentient, as it tried several times
to strangle, trip, or ensnare me as I was working on it.
I look forward to attacking this worthy opponent again in
the spring ;-)
Same thing happened to me, except mine did make it up to the transformer at the
top of the power lines. I had to cut the vine with a chain saw to kill that
section of it. I also have another one that's growing up a section on the rear
of my house. The vine has so many runner roots that small shoots are coming up
in the rest of my flowerbed along the back of the house and even out in the
lawn. I getting rid of this one this fall.

I have them, also, but they're not even close to the Bittersweet when it comes
to invasiveness. I must also add another one to the nominations. I'm not sure
of the exact name. Mom calls it a Cinnamon Bush, but I refer to it as a Spice

This trumpet vine I planted ran underground roots under a 20 foot wide
concrete drive and is now attacking my neighbors property. I had already
crossed under my concrete walkway and has been sending up runners about every
3 feet and climbing every bush and shrub it comes across. I have now resorted
to brush killer on every new runner and the original has been dug out along
with about 30 feet of roots. In the meantime, the feeder roots left behind
are sending up runners!! It's worse than kudzu!!
I bought a trumpet vine this summer and it is in a large pot. It has lots of
foliage but no blooms. What am I doing wrong? I live in Houston and
thought it would be a good blooming plant for an arbor but so far it has
Most likely too much fertilizer and too much water. If you look around town
during blooming season, you will see the most blooms on the vines coming up
through the asphalt and clinging to the sides of brick buildings or chain link
I think you are expecting things to happen a little too fast.
In the wild, a trumpet vine may spend several years climbing
a tall tree, and produce little more than foliage until it
reaches the canopy, where it sets in for serious reproduction.
Also it seems you are trying to constrain its size somewhat,
growing it in a pot, and I don't know how well that will work.
I am not sure if it will develop a robust enough root system.
Even if it is satisfied with its situation, I would not expect
blooms the first year. Start looking for that to happen more
like the third year.
