Great bunch of gardeners on Spark People!! Lots of people think it's worth the trouble to dig up the corms before frost -- and others simply treat as annuals and buy fresh the next year.
It's possible you might get somewhat the same effect with Lucifer crocosmia which are apparently hardy to zone 5? Depending of course on where you plant them too . . . out in the open less so than against a south facing wall.

And yes, both MOLLIEMAC & GARDENCHRIS have "nailed" both the flower & the lack of winter heartiness. Apparently, if the bulbs freeze, that is the "end" of that. But what a beautiful display along the side of that house! 9 days ago
hm, I was wondering if these were foxgloves...but i've never seen them red. likely the other folks were right about them being a type of lilies. did you discover what they are for certain? 9 days ago
canna they do have to be dug up and brought into a non freezing area like a garage, unless you are in a warm climate because they are tropicals, I have them in my garden and I am in zone 5 9 days ago
We have something here that has a similar flower but totally different leaves. It's called an Indian Paint Brush and it's beautiful too. Since it grows in the Colorado mountains it would probably survive the winter there. There are actually quite a few plants referred to by this name, but here's a link where you can take a look if you want an alternative to taking up the lilies every year.
