I have found a way to collect the seeds from my Blackeyed Susan Vine, being as I could only find green pods or husks where seeds had been I came up with this idea, I got some small self sealing plastic bags( the type buttons are put in on new garments) and put several seed pods into each bag still attached to the plant and sealed the bag up to the stems and waited until the seeds were ripe then cut the bag free from the plant with the seeds inside the bag, hope this will be of help to others.
