It's winter still and the roses aren't blooming yet but that's just what my wife needed for her sachets. Trying to find a florist with some old flowers that they don't want AND are willing to give them to you is really hard. The big chains are too scared to let anything go out for free just in case someone decided to put them in a stew and eat them, gets sick, and then tries to sue them for the terrible flower petals that weren't meant for consumption in the first place. Fortunately we were able to find some but only because the person who had them wasn't going to have the time to make potpourri herself.
This next growing season I'll just have to make sure I collect all of the petals our rose bushes put out so this won't happen again, but it probably will.
