Taking a deep breath, we're going to try a Hedychium outside this year.
It's the one called Tara and it will be in a pot 'sort of' in the lee
of the house and Tea Room walls but not tucked right into them. It
seems worth a try to see how it gets on and at least we do have others
if it does keel over. Watch this space! Apart from David P who has to
slash his way through his personal jungle, has anyone else tried this
outside over-winter and if so, in which location?

Sacha nearly all the Hedychiums are perferctly root hardy, we grow about
14 different species in the garden and apart from the more tender ones
flowering rather late have no problems at all with them, but I would
recommend in the ground rather than a pot if possible as the "for sale2
plants in their containers suffered badly last winter while all the
garden ones have flowered as normal
