Japanese Knotweed (Reynoutria japonica syn. Fallopia japonica & Polygonum cuspidatum) often mistaken for other plants, such as Russian vine or bindweed. Additionally, identifiying Knotweed by white flowers in summer, green stems with red and purple flecks and how quickly it grows. Likewise, new shoots appear in spring and can look similar to asparagus when they first start to grow.
The plant was originally found in Japan and controlled by natural pests and climate conditions. A sample of the plant bought back to Europe in the Victorian era, began being planted in gardens, mainly to create themed areas. The plant was found to grow quickly, and by the mid-1800s, was being sold by multiple sellers across the UK.
Since then, the plant has spread across the UK. The rhizomes (underground shoots) can grow to a depth of 2 metres underground, leading to this plant returning each year.
Japanese knotweed can cause damage to building structures by targeting weak points it can grow through cracks in masonry and buildings. The plant will then expand and grow into the crack, causing further structural damage.
Due to the rhizome’s resilience, animals can transport the invasive weed (via the rhizomes being moved via their feet), waterways, railways and main highways. Therefore classed as high risk due to this.
