Seed pod?

G’day all. I’ve not had this happen before and was hoping for confirmation and advice. Normally my Mexican pings flower,fade,die. This flower stalk is different. Is this a developing seed pod? If it is....what are my next steps? How will I know when the seeds are mature and ready for the next step of my adventure?. the pings self germinate as I only have one of this (P. Gigantea) and a couple other Mexican pings...
Thank you in advance for any advice you may be able to give me
