To hybridize your own daylilies simply remove a pollen laden stamen (there are six of these that will have thick yellow pollen on the end) from the plant, and rub it against the pistil (this is found in the center of plant and is surrounded by its own stamen) of the plant which you wish to produce the seeds. It's best to attempt cross pollination in the morning. Wait for a thick oval seed pod to appear, pluck it from the parent, and voila!
