I have great memories of my father, his pockets full of seeds from a hike. With a little work and research you can bring seeds home and grow them yourself . If you have a smartphone take a photo of the plant and note it’s environment. Then Google how dry it will need to be, if it needs to dry on the plant or if it can be harvested to dry in the house, if you should freeze it for later, and when and how to plant. It can be as simple as waiting to see the pods on plants mature and open , grabbing the stem below the pod, and shaking it where you want it to grow, or it could be a very controlled process. The results can be surprising, and you could end up with your own special hybrid. I said that point you give it your own unofficial name and continue on by sharing with others.
