Ginger - Zingiber - also Cautleya

To continue this discussion from an English perspective:

Zingiber mioga is hardy and does well here in this cold part of southern 
England (-12 C minimum for past two winters), though it has never flowered. 
It seems to have been introduced to the UK from Japan by HJ Elwes of 
Colesbourne, some time prior to 1915 when his specimen was painted for 
Curtis's Botanical Magazine. My plants came from Stokes Tropicals, however! 
I've never seen a variegated one in the UK.

Several Hedychium are hardy here but emerge late and seldom perform very 
well. They need more wamth and moisture than are usually available. This 
year we have had the warmth but no moisture.

Cautleya spicata 'Robusta' is reliable in the open garden, though looking a 
bit droughty at present. Other species have been swamped by other plants and 
have died out. (Self-sown Impatiens are usually the culprits).

Roscoea of all kinds do well and several self-sow abundantly (but not R. 
purpurea 'Red Gurkha'!), but they also need more moisture at present and are 
late this year. The yellow form of R. humeana is gorgeous at present,
