The ones in the first pick look like they're ready to open soon.
If that's your only plant, it might be fun just to let it grow (as long as it is your only plant) and watch the pods open and the pollen drop. Kind of a neat thing. When they first open, put a small piece of black paper or cloth under one of the pods and tap it. You will be amazed at the amount of pollen that a single pod can hold. Nature is pretty cool.
