Gladiolus: How hardy outdoors?

Hi all,

Lisa commented privately to me that she would try some of her gladiolus 
outdoors in the ground over winter.  I tried that last winter -- one which 
turned out to be very wet!  None of the South African species survived the 
wet winter in the ground:  Gladiolus oppositiflorus salmoneus and G. sp. 
indet. from Drakensberg.  Oh, yes, I kept some of the corms in the house 
over winter too!

G. x-gandavensis survived outdoors in the ground, but only one survivor of 
the several is big enough to bloom.  None of the various Gladiolus "nanus" 
cultivars that had been surviving there made it though the winter.  One 
purple G. x-hortulanus did survive, at least a few corms did.  None are 
going to bloom this year, however.  This is the "hardy" large purple garden 
hybrid glad that John Harris was distributing a few years ago.

Are there any other hardy Gladiolus anyone can suggest?
