|Fully mature spike of Hedychium gardnerianum|
I grow mine in a pot to give a better chance of flowering. It also allows me to protect the plant if winter does get harsh. All of which means I can move it around if needed. Currently it's close by my plant of Ensete ventricosum 'Maurelii'. Together they make a fantastic combination.

Hardiness is a relative thing, of course. This ginger is certainly root - well, rhizome - hardy through most of lowland UK, particulalrly if well mulched. The evergreen top growth isn't hardy except in very mild winters - but new growth will certainly come from the fat rhizomes by the end of May. The race is then on to produce flowers before winter sets in. Good weather this year has allowed growth - and the result has been glorious.
