morning glory seeds

Found a stash of morning glory seeds I guess the original packet I collected with this homeless guy that looked like a rockerfeller maybe he’s a rockafella. The first packet I might have kept and then went on to collect a majorly nice one I meant to draw and paint as a study but I lost the second packet on the way home. So glad to find this one cod the vines are all over the city you might find one in front of a church yard or playground. I have never tried them but I heard mixed messages.  So I won’t try them but what a horrible tactic. They look like black peppercorns.
