I planted one in our bog-garden and it's done very well for the last 12 years or so. When I say bog-garden, it's of my own making, only about 10-12" deep and lined with plastic sheet (punctured in places) with a timed watering system to keep it constantly damp. Works a treat but needs frost protection and feeding once in a while, I fold over the leaves and cover with a quilt. It grows to about 6 feet but is limited by the depth of soil. It is also surrounded by Tyfa Latifolia (great reed mace) and other bog plants. The plastic sheet prevents the nearby Phyllostachys Nigra Henosis (Bamboo) from spreading. My first attempt and as I am in my 7th decade I want easy maintenace, this has proved very successful.
