Hi John,

Japanese Knotweed is about 2 metres tall, with large (hand sized)
heart shaped leaves on pinkish / orangish hollow stems.

It has sprays of 'frothy' white flowers that tend to hang in fronds.

It grows like crazy, and has extensive underground root systems
which make it very difficult to eradicate, and the lush valleys of West
Cornwall are full of the stuff, which chokes out everything else.

We can't find Kudzhu in any of our extensive collection of reference
books. But the Latin name of the Japanese Knotweed is
REYNOUTRIA JAPONICA or
POLYGONUM CUSPIDATUM

There is also a Giant Knotweed, rarer, and up to 3 metres tall.
RAYNOUTRIA SACHALINENSIS

so if anyone can find the Kudzhu in their own books, check
the latin (botanical) name which should be universal ....
but isn't as you can see from my example above 8-)

John.
