The autumn display though short-lived is also striking. There are of course many plants with striking flowers and foliage that are not so invasive. Unlike at many locations, this plant would have been acquired at some cost and deliberately planted at Otterhead in Victorian times when the lost gardens of Otterhead House were being developed. Although very invasive, this plant has the dangerous ability to pollinate the flowers (all female in the UK) of Japanese Knotweed thereby producing more knotweed seedlings. However at Otterhead there are no known locations of Japanese Knotweed.
