How to grow

Cultivation This plant is subject to strict controls as an invasive non-native species under the EU Regulation on Invasive Alien Species. As a result the RHS strongly recommends gardeners not to grow it, and consequently do not provide advice on how to cultivate it. If it is already present in your garden there is no requirement for you to eradicate it, but you do need to take utmost care with managing it and with disposing of unwanted material
