Japanese Knotweed & Mystery Vine

bob64(6)October 18, 2006

I don't mean to seem ungrateful but I am wondering why properties down the street have japanese knotweed and ours (apparently) does not?

On another note, I noticed a smooth, thick, grey woody vine with almost no branches on the way up and small leaves, reaching straight up from the ground to the canopy of a large oak without touching the trunk. It is not grape, porcelain berry, bittersweet, virginia creeper or poison ivy. Sorry, no pics. Any thoughts on what this mystery vine could be. I am embarassed that I never noticed it in four years.

Could your mystery vine be either a trumpet creeper or an excaped wisteria? Both have smooth thick vines and only hold leaves high up in the tree. Are the flowers on the vine compound or not?

I think japanese knotweed prefers moist soil; maybe that's part of the answer. Maureen

There are some small vines nearby that look like trumpet creeper - maybe that's it. I had never seen trumpet creeper with a vine so thick around. The vine also looks a bit like some big wisterias I have seen in people's yards but I can't tell much about what is at the top because it is very high up in the canopy of the oak tree.

Because God has smiled on you, that's why. Do you want the awful stuff?
