Links to More Information about Japanese Knotweed

  Why reinvent the wheel?  Plenty of web sources on Japanese knotweed already exist, with information on its history, management, and lots of great photos.  Rather than spending time creating my own version, I've compiled a list of the best sites:
 
 

Comprehensive Sites

 
 

Fact Pages

 
 

Sites with Link Lists

 
 

Sites with Good Photos

 
  • Trace the growth stages of a Japanese knotweed rhizome, from spring resprout to fruiting, at The Knotweed Page's What Does it Look Like?
  • Visit the Mass Invaders Japanese knotweed photo gallery, 65 images and still growing!
  • The Virginia Tech Weed ID Guide has great photos of Japanese Knotweed
 

Other Good Links

 
  • History of the Introduction of Japanese Knotweed in Massachusetts (part of ConNE website)
  • Notes on Medical Attributes of Japanese Knotweed, by Joan Spainhour at Wilkes University
  • Description of Japanese Knotweed (plus recipes!!) from the books of "Wildman" Steve Brill (Note: if you decide to collect knotweed for eating, please be careful to consider how "pristine" the area is that you are collecting it from.  Many plants, including knotweed, can take up pollutants from the soil.)
