Height to 1m; spread....up to you!
A fabulous marginal plant for pond edges, wet spots etc. It does spread so should be grown in a container unless you want an area colonised.
A very architectural plant with tall, upright stems with a striking banding. Couple this with an extraordinary natural history....and that it has been classified by the boffins as a fern..... it is pretty much a must have... just remember to contain it! It is superb in containers.
