Japanese knotweed (Fallopia japonica): an analysis of capacity to cause
Fallopia japonica (Japanese knotweed) is a well-known invasive alien species in the UK and elsewhere in Europe and North America. The plant is known to have a negative impact on local biodiversity, flood risk and ecosystem services; but in the UK it is also considered to pose a significant risk to the structural integrity of buildings that are within seven m of the above ground portions of the ...
Japanese Knotweed: Compounds, Uses, Safety, and More
Japanese knotweed ( Fallopia japonica) is a perennial herb native to parts of Asia. It has been used in traditional medicine for centuries, although scientific evidence supporting its health benefits is limited. Parts of the plant (e.g., roots, stems, leaves, and flowers) contain many bioactive compounds thought to benefit human health.
PDF Japanese Knotweed
in the winter (Beerling et al., 1994). New shoots will emerge from rhizomes in the spring. Monocultures of Japanese knotweed have been seen after stands are established. It has been observed that the presence of Japanese knotweed reduces local species diversity, providing evidence that it can suppress forest regeneration (Aguilera et al., 2010).
Elucidating the Population Dynamics of Japanese Knotweed Using ...
Introduction. The impact of Japanese knotweed (Fallopia japonica, Polygonum cuspidatum, Reynoutria japonica) has been recognized throughout Europe and North America [1,2].Riparian and disturbed areas are especially vulnerable to invasion by Japanese knotweed and other weedy species because of an influx of nutrients, plentiful light, and frequent deposition of new propagules [1,3,4].
New Japanese knotweed standard comes into effect
On 23 March, the new RICS Japanese knotweed and residential property professional standard comes into effect. By complete coincidence, that date is exactly ten years since its predecessor, the information paper Japanese knotweed and residential property, was launched. That paper introduced the first formal process for assessing Japanese ...

PDF Japanese knotweed in Minnesota
Japanese knotweed, Polygonum cuspidatum (also known as Reynoutria japonica or Fallopia japonica), is a perennial, shrub-like plant that can grow up to 9 feet tall. It is one of four knotweeds that may be encountered in Minnesota, which includes a dwarf variety of Japanese knotweed (var. compacta), giant knotweed, and Bohemian knotweed (a hybrid ...
Cornell Cooperative Extension
Japanese knotweed stems are hollow and jointed. The leaves are alternate, broadly egg-shaped, and 3 to 6 inches in length. The plant is dioecious, so male and female plants both produce cream-colored flowers that vary slightly in appearance. Flowers appear in late summer and are found in erect clusters 4 to 5 inches long arising from the leaf ...
Research Breakdown on Japanese Knotweed
Japanese Knotweed, or Polygonum cuspidatum, is a Traditional Chinese Medicine used for circulation and heart health. It is a very good source of resveratrol, and most benefits of Japanese Knotweed may actually just be benefits of resveratrol. Japanese Knotweed is most often used for Cardiovascular Health and Healthy Aging & Longevity.
Japanese knotweed
Japanese knotweed is a tall dense shrub that can rapidly grow to a height of 3-4.5 meters (10-15 feet). Arising in the spring from spreading underground rhizomes and a deep taproot, the hollow jointed stems are reminiscent of bamboo and assume an orange hue when mature. The simple ovate leaves are borne alternately along the stems and reach up to 15 cm (6 inches) in length.
'Hybrid' Japanese knotweed that can grow from tiny amount of plant spotted
One such hybrid is Giant knotweed, which features exceptionally large leaves, heart-shaped leaf bases, hairs underneath the leaf, and lengthy, fluffy flower clusters. These plants bear a striking resemblance to hybrid knotweed, but are significantly larger. They can reach heights of up to four metres, with leaves that can grow between 20cm and ...

Homebuyer has second thoughts after spotting concerning weed spreading
Japanese knotweed is considered an invasive species across the U.S. Originally from Asia, the fast-growing plant competes with local flora for resources, eventually overtaking the surrounding plant life. This creates a detrimental domino effect in which other local species, such as birds and insects, leave the area due to habitat and food loss.
What happens if you don't deal with Japanese knotweed?
It's during the summer months, that Japanese knotweed becomes fully formed with "large shovel shaped green leaves". Leaves can grow up to 200mm long and the canes grow to around 3 to 3.5m tall.
