Gladiolus: How hardy outdoors?

I'm not sure how deep I planted them; probably 4 to 6 inches.  I'll try 
some more of the Glad. oppositiflorus salmoneus in the ground next spring, 
as I have plenty of these seedlings.  We of course get a lot colder some 
winters, and our ground can freeze as deep as 2  or 3 ft.  Fortunately, it 
rarely freezes deeper than 4 to 6 inches, which is what it does most winters.

I suspect it is not the cold but the wet we had last winter that did them in.

If you come across a source for genuine Gladiolus saundersii, please let me 
know.  I really want to try them and try crossing them with G. opp. 
salmoneus to test for winter hardiness here.
