I love them too. That pink is so pretty. When a flower falls off, it will leave a little round wheel like seed pod. Leave it alone until it turns brown and opens easily. In each wheel, there will be numerous flat seeds. They are easy to find and harvest. Good luck. I don't know if it will be the same color. Maybe it will be pollinated by a different color and you will get a new colored hh. Not sure how that works with them.
