Hello, I have never planted anything from seed. I have an oenothera triloba (I think). It's the flower that looks like a weed, but flowers only once, at dusk, and opens before your eyes. The small plant that I have now has what looks like seed pods at the base of the plant. It is in a small pot. I would like to save the seeds to make another plant. I would appreciate any help as to when to break the pods off, how to store, and when and how to replant. I am in the Sandhills of NC-- Zone 7.
