OK, either you two are feds trying to entrap someone or you are yanking our chain.
You know if you plant the seed, you have to be sure not to scratch the seed capsule while it is still green otherwise milky sticky sap will leak out, no a different kind; FOCUS! stay on task here, lift your minds out of the gutter, where were we? Oh yeah. Never scratch the green seed capsule, especially not with something serrated that would make a whole bunch of scratches at once. That would be really bad because then a whole lot of milky sap will leak out.
If that accidentally happens, don't worry, the sap will sort of clot, like blood does, and then it will turn brown. You may want to clean the brown stuff off so that the green capsule look nicer and more tidy for when they dry and you PUT THEM IN YOUR FLOWER ARRANGEMENT, right? that's the whole point. Dried flower arrangements.
So, after you've cleaned all the brown, resinous sticky icky gook off your nice pretty seed pods, you'll probably find that you have a whole bunch of the crap to get rid of. Probably best just to burn it because if you throw it in the trash it will just stick to everything and make a worse mess. Just be careful when you burn it, keep the fire small and in control.
Good luck and happy gardening. Here's an Ikebana flower arranging site with tips on arranging those dried seed pods:
