(I'm now contemplating cutting some to prepare for a mock-rhubarb pie, as
some sources I found say it's even better tasting than rhubarb!)
I'm sorry I don't have the information you were looking for, but I found it
interesting that it's found on hillsides and is used to stabilize soil and
therefore, I suppose it could be useful information for landscaping to help
Here is the site where I found some information.

Japanese knotweed is not seen as an undesirable weed by all. It is a popular
ornamental across the world. When used as an ornamental it is often called
fleece flower and is often given a glowing recommendation by magazines and
catalogs. People have no idea that soon after it is planted in their flower
gardens, the issue becomes more of how to eradicate than propagate the
In Japan it is used extensively to hide garbage dumps, pigpens, waste areas,
etc. (Jennings and Fawcett 1980). In sandy seashore areas Japanese knotweed
is often used to stabilize soil as it can easily withstand the spray and
wind and low soil nutrients as few plants can (Locandro 1978). The plant is
edible; when the newly emerged shoots are picked they can be prepared like
rhubarb. It is said to have a unique almond flavor. Bee keepers have planted
it for its abundant nectar secretion (Locandro 1978). The plant has some
medicinal purposes and has been used as a fodder crop, but rhizomes are
reported to be toxic to some species of livestock (Beerling et al. 1994).
During World War II, Japanese knotweed leaves were used as a substitute for
Norie, on a leisurely Saturday trying to catch up with this active list!
