I've planted as late as January and got flowers. As long as they are still firm, you should try. Why not pot them up in damp soil and keep them in your garage? Keep them cold but don't let them freeze. Whatever they grow into, plant them later on in the garden. Whether or not you get a good show out of them this year, they may do OK next year.

All spring blooming bulbs need a prescribed period of cold in this neck of the woods. Depending on how many you bought...follow loretta's advice (risky at best) or toss 'em and start over next year. Just as a side note, I treat tulips as annuals. I pull and toss every year when I can plant them at all due to squirrels and deer!

Do it! : ) I will be surprised if you get anything from the anemone but if the crocus and daffodil are mostly healthy, they should survive. If there is a little rot, wipe it away.
The reason not to let them freeze at this point is that they will turn into mush especially in pots.

Daffys, crocus and some anenomes are reliably perennial. I would plant them as soon as you can, either in pots in the garage or in the ground if it's unfrozen.

You may not get flowers this year, but you never know... and next year they will be beautiful.
