Hi, Suzi
That is an interesting question.
I freeze seeds to preserve them for later use so I would say if the seeds were mature, freezing would possibly not hurt them.
If these were my seeds, I would pick them, bring them in to a place where the seeds can thaw out and dry them thoroughly.
I hope this works out for you.
