Answer: Your bower vine is producing seed pods and if you allow the pods to dry on the vine, then cut them off and break the pods open, you can collect the seeds. Each seed has the potential to produce a brand new bower vine. If allowed to remain on the plant, the pods will eventually weather enough to open on their open and spill seeds on the ground. If this happens, you'll have lots of new bower vines growing at the feet of your original plants.
