I had a giant pod last year and when I finally opened it there was nothing inside. So when I got another giant pod on a different plant this year I assumed it was the same story. I let it alone forever and it still wasn't drying up and splitting so I wanted an end to the mystery and opened it. To my chagrin it was full of fat tan seeds. I am assuming they are too immature to grow, what do you think?

It won't cost anything to give them a try........it would have been better to let them go until the pod was brown and beginning to crack.

I knew someone was going to say that! I was hoping that maybe someone else had good luck with seeds like this.

Did the seeds fall out of the pods easily or were they still attached to the pod wall? If the seeds were loose in the pod, they are mature. If not, they still might be OK as they are pretty close to mature by the time they start turning color. You might go ahead and dry them out. If they turn dark brown, they are likely good. If they are still light tan after drying, they may not be viable but you never really know until you plant them.
