What is the holiday that the florists give out a dozen roses to give away to others?

I remember a few years ago when I was in college, people were handing out roses that they had gotten from the florists for free. I went by one to figure out what it was about and it was some sort of holiday where the florists gave you a dozen roses as long as you signed a paper saying you would give them all away. Does anyone know what this day is and when?
Okay it’s not one of the regular holidays like mother’s day or valentine’s day or easter (btw, that’s a dumb answer). It was something like friendship day or amnesty day or something odd like that
