All you can do is maybe soak them for a few hours before you plant them, then hope for the best.
One of two things will happen, they'll come up and be nice or they will not.
For future reference, keep them in a cool spot, enclosed in a bag or box with peat moss, wood chips or something, or even in some barely moist potting soil in a pot. If it's cool enough they won't rot or go moldy. You want to replicate what they would get if they were underground in a garden during their dormant time, so a little water isn't out of place.
