those are some lovely flowers! congrats!
when the seed pod ripens, it will dehisce (split open) and release the seeds. the seeds look like specks of dust because unlike most seeds (like beans), they contain very little nutrients for the plant embryos. it's a pretty elaborate process to germinate these in the lab, but under the right conditions it's possible to germinate them outside. the threads in the Propagation Subforum has lots of information on both methods (mostly the lab method), and so do other websites that you can find with a simple google search. it will take several years before the seedlings reach maturity, however, so keep that in mind if you end up wanting to germinate the seeds. no matter what you can continue to enjoy your current plant.
