Hi Jim:
I had no problems getting commercial Gladiolus cultivars to return in
zone 7 of southern New Mexico. Over time they would dwindle out but I am
not sure it was a winter hardiness issue.
In northern Illinois I have a single corm of Gladiolus byzantinus
(Gladiolus communis ssp. byzantinus) that has come back for a couple of
years.
We have some wild collected Gladiolus taxa from Republic of Georgia but
the corms (from seed) have not gotten large enough to test them
outdoors. Then, of course, we have a bumper crop of chipmunks that seen
to prefer bulbs of know wild origin - which is another reason they
haven't gone out yet.
