Hedychium gardnerianum.

Rhizome available by post Nov-Apr at £10 for enough material to make a plant that will start the next season in a 3 litre pot.  Come and see if I have one at a fair or show. 

This is very much one of those plants that photos don't do justice too. In my experience this plant needs a nice hot sunny season to really perform but then I'm in Manchester so that may not be true elsewhere.
