The behavior reminds me of my devil in the garden, wild Morning Glory.
It flowers briefly in late summer here in Connecticut. Otherwise, it spends
its time growing and wrapping itself around any and all neighboring plants.
I think I've also heard it called bindweed and chokeweed. Could this also
be named potato vine in your area?
/ The feature which sets my potato vine apart from the wild morning glory
and bindweed is its lack of a flower. I have it in sun and varying degrees
of shade and I've never seen a flower on it. (Can't compare it with
chokeweed because I've not found a picture or definition of that vine.) A
Guide to the Wildflowers & Ferns of Kentucky (Wharton and Barbour)
describes potato vine (ipomoea pandurata) as follows: "The trailing or
climbing stems of this vine may be 15 feet long. The flowers are 2-3
inches long, and the leaves are heart-shaped at the base. This is a very
common and troublesome weed in waste places, along roadside, and in
thickets throughout the state." However, once again, this differs from
mine in that it has blooms, and the leaves are somewhat more elongated than
mine.

Margaret,
Be very grateful that you have never heard of potato vine. It's the bane
of my gardening efforts. This subject was up for discussion on this list
before. At that time, I queried the list members about it and apparently
no one on the list (other than me) knew of it. It is listed in the
Kentucky Wildflowers book, but the pictured one has flowers (which mine
does not have) so I guess mine is a nonflowering variety of that one. It
is impossible to pull up. When you try to pull it, the leaf stalks break
off and some of the vine can be broken but the roots do not come up. It
spreads like wildfire. My mother had it in her flowers and I guess I
unwittingly brought some home when I transplanted something from her house.
I believe it gets its name from the tiny objects that look like very small
potatoes and grow near the roots . (Yes, occasionally one can pull up a
vine with roots attached, but rarely.) Either it is native to only a small
area of Kentucky or other gardeners know it by another name. I also called
the lady who writes the gardening column for the Louisville Courier-Journal
and she didn't seem to know what I was talking about.

What is potato vine? I never heard of it, and none of my references to
weeds mention it. Margaret L
