LOL Typ, "Deadheading with a purpose", that's what I call it, and I do it ALL the time at work! I have brought home so many packets and baggies of seed heads from work that it's just silly. This year I decided to "cull the herd" a bit... shared many with friends at a semi-local seed swap, and most of the rest I just haphazardly sprinkled liberally around my own "Big Bed". I hope the other recipients had better luck with their seeds than I did 'cause I got darn near squadoosh in germination!
Just tell your DH what I tell mine: "Hey, free plants, how can ya argue with that??"
