If you have the bulbs, and they are not soft and pulpy, then plant them. They won't grow in the shed and they might in the garden.

Thanks, you are right that they won't grow in the shed. Even if they did, they would be hidden by clutter!

They seem fine, quite firm and just as when I bought them actually. I could put them in the freezer to stimulate them, maybe?

Nothing ventured, nothing gained, try them? I'm always putting things in at the "wrong time", they may miss a seasons flowering while their biological clock gets back into synch but they should be ok as long as they aren't rotten.

Don't freeze them, just plant them asap.

Thanks everyone.
