That looks like a seed pod! Congrats!

seed pod. When it cracks open, you get seeds

Yes that's a seed pod! I found one in Mexico 3 years ago. My mother hid the seeds in her medication to bring them back. She was able to sprout 26 of the 32 seeds weeks later :]

Awesome, thank you all for the info, now to wait a couple years and see what colors emerge from the new growth
