I mean, I know they "can" be picked but will the seeds be viable? I picked some from a friend's yard. Could I let them dry in a paper bag or something.
Sorry, I'm quite new to seed saving ; )
I wait until the pods have dried (brown and papery)to remove the seeds. If you plant them right away, soak the seeds in water for a couple hours before planting--most seeds come up in 3 or 4 days.
I just did that experiement and the green seeds germinated better than the brown seeds - I dont think they last too long.
