I also saved some seeds from an OP Daikon Radish 'Minowase' that went to seed years ago when I planted it at the wrong season. Those seeds know the RIGHT season, and have been surprising me ever since by growing in my rock-hard clay and drilling pretty deep all by themselves.
These are also really easy seeds to save! I pulled some "weed" radishes that had a few pods, maybe ripe and maybe not. I dropped them in a corner of the deck until I got around to carrying them to the compost heap. That was enough "care" for them to finish ripening and drying.
When a guy came to tear up my deck and haul it away, I had to throw them somewhere else to get them out of his way. I forget what that was, but I had to jam them in to make them fit.
Abracadabra, "saved seeds".
So I rubbed the pods a little to get more seeds, and now I have them.
Just about the only thing they did not do by themselves was to put themselves into packets and label themselves.
