Those are glories,my same species,so it seems.yeah ,some years they won't bloom,and sometimes they will.And once in a great moon they will produce seed,but that is as rare as finding peyote growing in your backyard,hehe.Now they say this plant contains lsa.no seeds?how would you ever get any then? My theory is,when it finally does seed,wich is rare,they will be a potent seed,you think?This is amongst the strangest morning glory I've encountered.I'm going to find it's exact species.I'll post back later.PEACE
