I noticed this pod looking thing growing out of one of my plumeria plants and was wondering if anyone knows what it is.

Lynzib07, congratulations, you have a seedpod. It will stay on the plant through the winter dormancy and open just around the time the rainy season starts. It would help to know where you are located!

Thank you so much 😊 so should i just leave it alone? And I'm in southern California.

Yeah, it is not likely to start opening until spring. At that time it will start to look dull and might show a crack. Then you know it will open soon.

Thank you for your help
