I, too, was most concerned when I read your posting Barb. Japanese
Knotweed is certainly something to be avoided at all costs - it pushes
through tarmac etc., etc., and I totally agree with Louise that it should be
discarded. However, I looked up Fallopia japonica variegata in my RHS
book. F. japonica variegata is not listed, but it does state that F.
aubertii and F. baldschuanica may be difficult to control. I did notice
that Fallopia belongs to the Polygonaceae family. On looking up Polygonum
found P. baldschuanicum (syn Fallopia balschuanicum), I found the common
name 'Knotweed' (we also call it Russian Vine and Mile a Minute). I can
only hope for you that 'Knotweed' and 'Japanese Knotweed' refer to two
separate plants.
I did see Japanese Knotweed a few years ago. As far as my memory will
allow me to remember, it has upright stems, about 1/2" diameter and it 4 - 5
feet tall. If your plant is a climber, like Russian Vine, rest easy.
I hope you can understand my ramblings and that the above helps.

If this is the Japanese knotweed that we have here in the UK
(and I don't know our ones botanical name) throw it away
immediately. It's impossible to get rid of it. (Perhaps
someone else over here knows the botanical name for our
Japanese knotweed). This is the most dreadful invasive
plant introduced to the UK in the last 150 years - was
introduced by Victorian gardeners for their streamsides.
Sorry to be so depressing.
