You could plant some. (I'd suggest a south facing wall, as I even had 2 patio dahlias come back after last years harsh temps.) and mulch well.

Pot some up, store in garage,

Try to trade a few at the Bulb Exchange, or the Plant Exchange gets a lot more traffic, and trade for some bulbs hardy to your area.

Maybe plant out 'after' the worst of winter is past and the soil has thawed.

Oh, I have lots of daffs planted in the woods and they are not bothered by the shade, as the leaves aren't on until blooming time or later. Maybe they wouldn't need full sun so long as they weren't in the shade of a building.

Good luck...they sure are pretty.

Thanks, Sue. I have planted a few and am still trying to decide on the rest. I don't think I could plant some of them in spring: I know myself too well. I would never go out while it was still cold. I have promised myself this several times and have never done it. Cold mud is my least favorite environment. Planting them in pots seems like the best alternative.

I wonder if planting them deeper than the recommended 3" would protect them? They are small bulbs but 3" is awfully shallow.

I think I will try them in several places and do an unofficial "Brodiaea" hardiness test...at my expense! I know it's my fault for ordering them but I wish Van Engelen could have tipped me off when I forgot. Once before I ordered from a company and when one plant group failed to arrive, I found "Not hardy in your Zone" or something similar on the invoice. I was grateful!

I'd try to plant them 6-7" deep, but in your zone grounds will be solid frozed at that depth anyway and I wouldn't put much faith in a deeper planting.
Planting in a pots probably will be your best bet. Even in a pots plant them deeper than 3", otwerwise they will be too tall and floppy.

I'm agree with Sue that you can plant them in a protected area, a south facing wall. I have planted stuff that should be tender in my area (ex: Red Lion amaryllis, dahlias, eucomis, etc), forgotten to dig in the fall & survived. And that was without extra mulch since I hadn't planned on leaving them. I'd go for it & just mulch well.
