Plumie Friends!

I know this is off topic, but I am hoping that someone here might be able to help. I can't seem to find a seed pod on any of my plumeria, but...I have a seed pod forming on my small brugmansia plant, a no id yellow.

It was started from a cutting about a year ago. I have no other brugmansia, there was only one bloom, and I'm not sure how this got pollinated. Do these self-pollinate? Are the pods like plumeria and take months to mature? Right now, it looks like an okra...any information would be helpful.

Thanks!
