Japanese Knotweed is the most invasive plant growing in the UK today. It can grow up to 10cm per day. The Rhizome (root system) below ground is the biggest problem with Japanese Knotweed. The plant is capable of undermining drains and other under ground services and finds weaknesses in concrete / foundations allowing the plant to cause damage.
